100VA
To determine how many 12-volt, 50-watt bulbs can be used on a 100 VA transformer, first convert the transformer's capacity from VA to watts, which is effectively the same for resistive loads (100 watts in this case). Each 50-watt bulb requires 50 watts, so you can divide the total available watts by the wattage of one bulb: 100 watts ÷ 50 watts/bulb = 2 bulbs. Therefore, you can use 2 of the 12-volt, 50-watt bulbs on a 100 VA transformer.
In a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load. The volt ampere is used to measure the apparent power of a load, and is determined by multiplying the supply voltage by the load current. So the relationship between the watt and the volt ampere depends on the power factor of the load. For example a 100 VA load with a power factor of 0.8 (leading or lagging) will have a true power of 80 W.
Watts (W) is calculated by multiplying Volts (V) times Amps (A), so 1W = 1VAAnswerIn a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load.

40 VA is the apparent power of the load. It is simply the applied voltage multiplied by the resulting current in amperes. Given the VA and the Volts merely divide the VA by the volts to get I=VA/A = 40VA/24V= 1.667 Amperes rms. Andy B
Power = current * voltage. Multiply your supply voltage by 100.

k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA

VA stands for Volt-ampere. 1 VA is equal to 1 Watt. So 600va is about 600 watts. This can be confusing because a power supply rated at 600va will not put out 600 watts due to reactance. The power supply contains an inductor or capacitor so the actual output will be around 1/2 to 2/3 of the VA.
Electricity has three terms. Active power - Watt. Apparent power VA, reactive power VAR. Watt is known as active output
