It stands for volts alternating current.
A 'volt ampere' (not 'volt amp'!) is the unit for theapparent power of a load in an a.c. circuit. It is simply the product of the supply voltage and the load current.
Milli volt is one thousandth of a Volt and Milli amp is one thousandth of an Amp. Volt and Amp measure two different things and are not really comparable. Over simplified, here is how it works. Volt measures the 'pressure' that causes current to flow. Current flow is measured in Amps and depends on the how much resistance the 'pressure' has to overcome. Higher the resistance, lesser the current (Amp) for same pressure (Volt)
if its a single current its 120v X 25 amp = 3000 watts
That depends on the amp. if it has a very small current, it will only feel a little numbing.
Sure
It is just product of voltage and current at unity powerfactor(UPF) or power at UPF. 1kva is one kilovolt amp or 1000 volts at 1000 amps.

Research. Call transistor manufacturers.
Kvar stands for killo volt amp reactance.
Amp, Amperes is current. Volt, and any variation, is tension. There's no direct translation between them.
resistance = volt / current . 440 volt across a parallel circuit means the same 440 volt across both resistance s. hence resistance r = volt / current . 440 / 20 amp = 27.5 ohms total resistance
In North America 120 volts, in the UK and Europe 240 volts.
AMPERE, Its the unit of Current. AMPERE, Its the unit of Current.
ampere. It measures electrical current.
To do this you need to study how to use thyristor-control for power circuits.
No. At 125 volts, the same 15 amp current results in 10 times as much power. Ohm's Law states that amps x volts = power.
