- Q: I cannot see that a electrode would be useful in a generator, is there a way?
- According to Wikipedia: An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). There is an example of an electrode used in generators, and all industrial/commercial electrical systems. It is called a grounding electrode. It is a metallic rod that is driven deep in to the dirt, to establish a contact with the background Earth voltage. Is the dirt a nonmetallic part of the circuit? Well, dirt often does contain metals in it, but it isn't dominantly metal, so it still is considered non-metallic. And we normally hope that the dirt isn't part of the circuit, but there is a chance that it can become part of the circuit, and that is generally why grounding electrodes are installed. The grounding electrode doesn't really play an active role in the operation of any of the electrical equipment. It is more of a safety feature, as a JUST IN CASE the insulation on the live wire fails. Suppose the live wire insulation fails, and the live wire contacts the metal structure of a device (that isn't intended to play an electrical role), and you as a human victim touch that metal structure. You are also standing on the ground, and the natural path of electric current from the metal structure to the ground is through your body. Unless of course, a better path is established in advance. And that is what a grounding electrode, and the rest of the grounding system does. It establishes electrical continuity with all metals that aren't intended to be electrically involved, so that any failure of the live wire will trip the circuit breaker before there is a chance that the human gets injured.
- Q: Hey, I need to find out different electrical equipment used in a Beauty Salon and I can hardly think of anything! I can only think of wax pots and tanning beds :S Any other suggestions? Actual answers only please, don't bother writing Do your own homework or whatever because I really can't be bothered with people like that. Like I said I have TRYED and I cannot think of alot. Thankyou :)
- high frequency machine, bio face lift machine, ultrasound machine, beauty studio, brushing unit, galvanic machine are few of the machines used
- Q: hi i have a black glass tv stand which makes the dust very visible, i normally wipe with a cloth, but i don't really want to do this like every time it piles up with dust, is there a thing which removes dust automatically (please give me a link either OKorder or which supports pay-pal) thank you
- You could turn your Living room into a clean room, and put on a bunny suit every time you go into it!
- Q: and which one to use in my country Egypt ?
- NFPA - National Fire Protection Association - National code that covers anything to do with flamable stuff (electrical, dust, combustibles, sprinklers, fire alarms, etc) (United States) NEC - National Electric Code a.k.a NFPA 70 (NEC is a section of the NFPA code) - Addresses proper installation of electrical equipment, devices and wiring(United States) NEMA - National Electric Manufacturers Association- trade organization for electrical manufacturers. Sets common rules, practices and certification for the manufacture of electrical components and devices (United States) IEC - International Electric Code - International version of NEMA IEC would most likely cover devices made for use in Egypt. I'm not sure what organization or governing body would address the installation there.
- Q: A. Identify only the primary source of electrical energy for the equipment or circuits in question.B. Enable backup energy sources, such as generators and batteriesC. Make sure all workers are safe and accounted for before equipment and circuits are unlocked and turned back onD. Avoid testing equipment and circuitry to ensure they are de-energized
- picked B and got it wrong. :( its either D or C
- Q: I want to run an appliance that uses DC 5V 2.5A at 6 watts consumption using an adapter from the cigarette lighter socket. I have a standard 12v car battery in the small car. Do i need to get a bigger battery/more batteries, special alternator, or something else to run this appliance permanently?Is there an online calculator to help me work out how much battery power i need?Many Thanks to all answerers.
- See your APP. Wattage is 6W So Current It will draw6/51.2Amp from the Battery. The Battery is already 12Volts. Check the AHR(Ampere Hour) of your Battery Divide the AHR by 1.2 The max hour you can use that battery when It is fully charged.
- Q: Hi!Is there an NEC section which addresses the following kitchen design? I'm working with an apartment complex and they've designed each unit's breaker box to be located directly over the stove top burners. Something just sounds real bad here - but, perhaps I worry about things melting when water is brought to a boil or the oven is at 450 F for an hour or so and the vent for the oven is directly through a back burner. [The door for the breaker box just clears the top of the stove top.]Thank you!!
- Since you already got another answer that didn't address your question directly. I believe there is a code that says there must be so many inches of clear floor space in front of any electrical service panel. I believe then that your example may violate that code and may not pass inspection if there is one in place for your area.
- Q: i am instrument electrical eng.student and i am about to take 2 of the 4 subject for electives, here the subject:1)process control2)automation and robotic3)measurement and instrumentation4)control system 3i am thinking to involve in maintainance,oil and gas or maybe aircraft maintainance.after grad.what is the subject is suitable and what is the subject advantage and disadvantage. i want get some advice before make the decision.tq
- Well. it is very good major Oil and Gas companies need ur major since the instrumentation is controlling the whole units. Huge Essential System and very critical in any refinery such as: DCS : Digital Control Center. ESD: Emergency Shutdown. UPS: Uninterrupted Power Supply ( Electrical Equipment feeds instrument load) I think u have a bright future with this discipline if you have interests . And regarding these Subjects, i dont know much about control All the best
- Q: I know water can damage electrical equipment, but why can water do this? I'm sure it has to do something with electricity and water. I seek an in-depth answer that will leave me with no doubts, or further questions, if possible.
- Water is a polar molecule and in nature contain impurities which enhance it's conductive ability. So water become a conductor when introduced to electronic devices and electricity follows the path of least resistance, which is no longer the desired circuit. So with the electricity being conducted into places that are not desired it often causes components to fail by overloading them with power. Electrical equipment that gets wet while not connected to power often can be used provided it is allowed to dry out completely before power is applied. For example I have been know to put keyboards in the dishwasher and as long as I wait before I used them afterwards. But pour a cup of coffee into the ketbouard while in use and generally it is toast.
- Q: I am just a few classes away from getting my Associates in Electrical Engineering. I currently have a Diploma in Industrial Electricity and have been working in industrial maintenance for 12 yrs. and am currently an electrical technician (10 yrs. multi-skilled and the last 2 yrs. strictly electrical due to a job change). I have returned to school to get my AAS in EE, so I would really like to know what possibilities I could expect.
