Q:I have a 1992 F-150 with a 5.0 302 in it. Last week she started going haywire. My battery wasn't holding a charge, my spedometer was bouncing up and down and my mileage read was coming in and out. I had the diagnostics test done from Auto-Zone that tested your battery, alternator, and starter. They said that my alternator had low power output but everything else was fine. My dad (he's a mechanic) said I had to replace my voltage connectors on my alternator. We did that and she acted fine for about a week. Battery was holding a charge, no problems at all. A couple days ago, my battery light popped on and the battery is not holding a charge AT ALL. I constantly have to charge it. Any ideas on what the new issue could be?: Batteries do not hold a charge forever. If there is a power drain somewhere in the vehicle, like when you start the engine or run the headlights or the radio, you have to recharge the battery to keep it topped off. Your alternator should be doing this automatically as you drive. I have no idea what you're talking about Voltage Connectors in your alternator, but if your alternator is not keeping up with the demand of the electrical equipment that is installed in your vehicle, it will continue to draw down the charge in your battery until it goes dead. Have your alternator tested under load, and if it shows low voltage again, it's time to replace your alternator.

Q:and how does its work?: It will basically provide safety protection from electrical shock. Occassional large electrical equipment may become temporarily energized --- maybe a down power line, or by accident. By grounding the equipment, the earth that you are standing on, and the equipment will always be at the same voltage. Therefore, even if the equipment becomes energized at 25000 Volts, the ground you are standing on will be at 25000 volts as well. So there is no potential difference and therefore, no electrical shock. Without the earth connection --- there would be a 25000 Volt potential difference, and you would suffer severe electrical shock, or even death. Excerpt from Wikipedia: Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment (the terms ground (North American practice) and earth (most other English-speaking countries) are used synonymously here). Normally a grounding conductor does not carry current. Neutral is a circuit conductor (that carries current in normal operation), which is connected to earth (or ground) generally at the service panel with the main disconnecting switch or breaker.

Q:i want to make a bulb on and off at intervals of say half an hour. readymade timers available in shops(india) costs much and does not support shorter intervals like half an hour. any cheaper electronic circuit which can do this control? from where can i get the circuit or its diagram?: Depending on your skills, a CMOS 555 timer chip could probably drive a solid state switch (triac) for this interval although a more reliable timing, especially if you want exactly a 50% duty cycle, by feeding the timer output into a counter, so that the 555 cycles say 32 times (once a minute about) for each change of state of the selected output. Smaller cycle times are more stable.

Q:I understand that the frequencies emited from cell phones can interfere with the electrical equipment in ICU's; however, why can't patients have regular phones in ICU's; regular chord phones shouldn't emit frequencies or do they?: I think it has more to do with courtesy for the other patients in the unit. Remember, if they are in the ICU, they aren't going to up to talking on the phone anyway. Those patients need their rest, the last thing they need to is to be disrupted by phones ringing all the time.

Q:How does electrical copper wires aid to temperature rise?! I don't think it is also associated with carbon emission as carbon emission mostly come from vehicles and manufacturing industry.: It takes energy to send an electrical signal down a wire, and the longer the wire is, the more energy you will end up using as a result. So longer wire more energy wasted in the wire. As most electrical systems are powered by mains electricity, and they are in turn powered by fossil-fuelled power stations, longer wires more energy wastage more carbon emissions from the power stations. So, carbon emissions are lowered if shorter, and therefore less, wires are used. Also, copper has to be mined which causes local environmental damage as well as carbon emissions in the production and transport of the copper. as carbon emission mostly come from vehicles and manufacturing industry. The breakdown of carbon emissions is actually approximately 30% Heating, 30% Vehicles and 30% electrical power. As 30% of emissions are due to electrical power, clearly, using less electrical equipment would reduce carbon emissions, presuming that there is not a shift to fully renewable power generation such as wind and solar. EDIT: Spongebob, of course its a made up termwords don't just pop out of thin air you know. Still arguing against AGW James? We've moved on.

Q:At around 11:30PM on January 23rd, 2007 as I was typing on my PC the lights began to flicker and my computer began turning on and off. The lights then became extremely bright followed by a booms outside then the lights dimmed so low it looked as if they were about to burn out. The house phone was on began to cut out and made a loud screeching sound and thensilence.These strange events lasted for nearly 15 minutes when a knock at the front door got my attention. It was a fireman informing me to shut off my computer if I had one because of electrical problems that were occurring in the area. I immediately did so.It was not until the morning I discovered that my two TV's, all three cordless phones, a microwave, two alarm clocks, my entire computer, VCR/DVD, DVR/Cable Box had all been destroyed due to the massive power surge they endured. After surveying each and every unit I learned that all appliances in every apartment was damaged or destroyed.Who is to blame for this?: In many states, the local electrical utility is responsible for delivering proper power to their customers and when they don't, they can be required to replace any damaged equipment. They get to sue people who cause them problems (like an accident that damages their equipment, which then damaged your equipment). You should contact your local utility to see if they will voluntarily replace your losses, and if not, then contact your state power utility regulators to see if they can be compelled to. You, as a public utilities customer, should not be not required to foresee all of the possible power problems that might occur -- that's the utility's job. You probably ought to get a copy of any police or fire report of the incident that led to the fireman knocking on your door. That would probably help your case when you file a claim with the utility or state regulators.

Q:I cut a deal with my electrical shop teacher. If i tell him how we can relate an electrical class to ski lifts and snowmaking and learn about how they work and the electrical portion of them then hell take my shop to our local mountain Wachusett. Can anyone tell me how ski lifts and snowmaking equipment work and how i can relate it to electrical: Your electric drive motors run on high voltage. Three phase 480v. All of your controls and safety systems run on low voltage. Battery powered, 24 or 48 volt. This is so that the lift can operate properly in the event of a power outage that cuts power to the drive. Lifts have backup drives, usually a diesel generator that can supply power to the electric drive motor, or an actual gas or diesel motor that can be coupled to the gearbox and drive the lift itself. Controls are usually a programmable logic control that monitor proper operation of different components of the lift and through a series of relays send power to the drive. Snowmaking is as aforementioned powered by large electric pumps and air compressors. Air and water are pumped usually from a central location and piped around the mountain to hydrants. Here, the snow guns are connected to the air and water. Some types of guns simply blow the water and air to make snow, while some have motors on them. These plug in to electrical pedestals, high voltage, that are located at the hydrant locations. These power large fans that help disperse the water and also control oscillating guns.

Q:I don't know a lot about electricity, but I know that on earth we ground our outlets, computers, etc. Do they have a means of grounding electricity in space? Are electrical systems more dangerous on spacecraft?: We do not ground all electrical equipment. Much of it is double insulated. Grounding simply connects the chassis to Earth, so that if there is an electrical fault that makes the chassis live this is short to Earth and a person, who we might expect to be standing on Earth and not hovering, will hence be at the same potential as the chassis. The actual circuit is not grounded - its return path conencts to neutral. Precisely the same principle can be used in space, but in light of the fact that people in space may actually be floating, double insulation is safer.

Q:if you've heard of the wilhelm scream, is there an equivalent for an electricity crackling sound?I've heard it in Star Wars, many cartoons, probably Spider-man (it's like imagine when some big electrical equipment goes wrong and starts producing sparks, or when you have some space laser gun that stuns people).Any idea?: I think it comes from Frankenstein, with all that electrical equipment they used

Q:I don't intend to get a job with this but it would be good to know some things about it since everything runs on electricity now.: what kind of things are you trying to learn? General household appliance maintenance or would like to design your system to do something cool? You could learn both types casually if you are really interested.
