Watts (W) is calculated by multiplying Volts (V) times Amps (A), so 1W = 1VA
Answer
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.

What is 0.25 of a watt?
0.25 of a watt is equivalent to 1/4 of a watt, or 250 milliwatts. It represents a quarter of the total power output of one watt.
How many 12 volt 50 watt bulbs can be used on the 100 va transformer?
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.
Can you run a 250 watt motor using a 1000 watt controller?
Yes, you can run a 250 watt motor using a 1000 watt controller as long as the voltage and current ratings are compatible. Be sure to adjust the settings on the controller to match the motor specifications to prevent damage.
How much is a 250 watt amp worth?

How many amps can a 250 va transformer carry?
A transformer is a power source. It will provide voltage to a device. Find the voltage rating on the device, say 24V. 250/24 = ~10A.
