How many amps is a 500VA transformer?

VA to Amps conversion chart:

then, How many volts is a 20 amp circuit?

2400 Watts / 20 Amps = 120 Volts.

Beside above, What does 12v 10va mean?

So 10va means the tranformer will output 10 watts at most at 16 volts. Transformers only work on alternating current. The ratio of the number of turns around the core on the primary coil to number of turns on the secondary coil determines the voltage decrease or increase.

Considering this, What does 500va mean? It is simply the product of volts times amps giving a value of volt-amps, VA, as the answer. Example: You have a transformer that supplies a voltage of 100 volts AC and is capable of supplying a current up to a maximum of 5 amps.

What is a 40 VA transformer?

So the transformer would be labeled 40 watts.For the furnace you might be running a solenoid for a gas valve or motors for pumps on a boiler.40 VA means that it can deliver 1 2/3 amps at 24 volts.
