What else can I help you with?
What formula calculates the current drawn by the transformer for mains electricity?
p=r*i
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
How do electrons flow on an ac source?
With electricity from the mains, the current chages direction 50 times each second, so it is called alternating current.
What is DC in electric stand for?
Volts direct current eg battery As opossd to Vac wich is volts altinating current eg mains supply
What is sinusoid?
What is a sinusoidal wave? This is a wave that appears to have curves. AC current/voltage. If you see a wave on a ossiloscope of what our AC (Alternating current) mains voltage that will be the answer to the question. DC (direct current) does not appear to have the same qualitys
What is difference between battery and mains electricity?
Mains supply provides alternative current while battery provides direct current.
What you get from mains voltage or current?
You get power, which is voltage * current (so both!).
How can you test water coming out of the ground to see if it is mains water?
You can test the water for chlorine levels using a pool water test kit. Mains water typically contains chlorine, which is used to disinfect the water. If the water shows a chlorine residual, it is likely mains water.
What formula calculates the current drawn by the transformer for mains electricity?
p=r*i
Why is direct current used for mains electricity?
We're deeply intrigued to know where the questioner resides, and from what experience this question arises. We know of no location in the world, and no small-scale situation, where direct current is preferred for the mains supply.
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
Advantage of current limiting?
Current limiting is the practice in electrical or electronic circuits of imposing an upper limit on the current. The simplest form of current limiting in mains is fuse.
Who do you contact to have mains electric cable laid to your property?
The electrical supply authority for your area
What is the difference between mains electricity and batteries?
The first difference is that mains power is AC (Alternating Current) whereas batteries are DC (Direct Current). The second difference is the amount of available amperage; mains have the capacity to deliver higher current for an indefinite amount of time, where batteries will drain faster the more current is pulled. Your normal A/AA/C/D/9V batteries only produce 500 milliamps (1/2 an amp) at their nominal voltage (1.5 or 9v). Mains current (for the U.S.) is 110 or 220 volts in residential. Commercial mains, such as in factories, can be 110, 208, 220, or 440 volts. A big difference between residential and commercial electricity is the available phasing. But that's another discussion.
When connecting a mains polarity test between the neutral and earth connections what should the reading be?
Infinity
What is the difference between electricity mains current and the current from a battery?
Electricity mains current is typically AC (alternating current) and comes from the power grid, while current from a battery is generally DC (direct current) and is stored chemical energy. Mains current is continuous and requires a power source, while battery current is self-contained and portable.
How many amps are in mains power?
In most countries, mains power typically supplies electricity at 120 or 240 volts. The current flowing through mains power can vary depending on the electrical load, but it is typically around 10-15 amps for household circuits.
