- Q: I know you need fuses for cars, electrical equipments, etc. I don't get what they are really used for?
- Fuses are placed in the path of an electrical current as a fail-safe to prevent your equipment from frying. It is essentially a piece of metal that breaks when too much current is applied to it. What this does is stop the electrical current from getting to your radio/ECU and doing damage to it. Usually if a fuse has blown in your car it is a sign that something has failed and you should check the related system before simply replacing the fuse and repeating the process.
- Q: I have a 2000 Monte Carlo SS that is stock, as in no aftermarket radio/electrical equipment and the fuse for the a/c and cruise. I noticed it popped when I bought the car and each time i put the same size fuse in or a bigger one, it automatically pops. I pulled the dash apart and all of the connections are good so I'm not sure of where to go.
- You have a bare wire somewhere touching metal. That is the only reason a fuse will pop. It#x27;s a pain in the a** to find, but that is the only way you can fix it. Don#x27;t put a bigger amp fuse in! That is a sure way of setting your car on fire.
- Q: I am assuming that the car is running when the items are being used.
- Disclaimer: i don't understand something approximately autos! I recall whilst i became into youthful, we've been using abode at evening and each and all the lighting fixtures fixtures in my mom's van started out to dim. We made it very almost each and each of ways abode (we've been a lengthy techniques from abode) in the past the van died. It seems that it became into the alternator. You did not say if the automobile will start up back, my guess is that it will not. back, i don't understand something approximately autos, so it could be the battery, yet my guess is the alternator. solid success!
- Q: 1.What is Rated AC voltage? Why we would like to state Rated instead of Nominal?2.What is Nominal AC voltage?3.Explain rms value for AC voltage. What is it's relation to Rated/Nominal Voltage?
- Rated Voltage
- Q: If it is, why?
- A house is usually grounded through its piping systems that have generous contact with the damp earth, resulting in negligible resistance. An AC circuit alternately pushes electrons into the earth and draws them back out (60 times a second) for each separate phase similar to the power generation station. Electrons need not travel from power station to house and back full cycle. A separate ground wire (cable) would be required if the earth's resistance resulted in appreciable power losses.
- 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?
- interesting question. you are right regular phones do not/should not emit frequencies that would interfere with any equipment.as far as I know I do not know why you are not allowed a phone in your ICU, I have always had a phone link immediately.and that was in ICU as well how else is family supposed to stay in touch? I do not believe that it is dis-allowed as a general rule you might want to double check the reason the dr/hospital staff gave you. hope this helps to answer the question good luck
- Q: I have a hanging, pull-string electrical light in my attic. This is very standard stuff. I would like to purchase an electrical device that will screw into the electric light and give me an electrical outlet. Think of this as a device with the base of an electric light bulb and an electical outlet instead of the bulb. I thought I saw one in a hardware store 20 years ago, but I have no idea if this product still exists. I can not think of what it would be called with a technical name when searching for one on the Internet.My business application is to be able to plug equipment into my attic rather than running the cord into the main house.
- It's called a light socket adapter. There are many places that sell them. Take care not to overload the low-current lighting circuit though !
- Q: An example of something would be one light flashes and another light goes off. Or Lights that are already on, turn off, another one turns on, and lights flash, then the whole process repeats itself again after a while.
- A clock driven multi-pole programable time switch. They come in both mechanical and solid state flavors.
