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.

How many amps is 145VA?

To calculate amps from VA, you can use the formula: Amps = VA / Volts. Assuming the standard voltage in residential settings is 120V, then 145VA / 120V = 1.21A. Therefore, 145VA is approximately equal to 1.21 amps.


Does the primary winding VA equal the secondary winding VA when a transformer is loaded?

No, the primary winding VA does not necessarily equal the secondary winding VA when a transformer is loaded. The power output on the secondary side may differ from the power input on the primary side due to losses such as resistive and core losses in the transformer. The transformer's efficiency will determine how close the VA on the primary winding is to the VA on the secondary winding.


500VA is equal to how many watts?

Oh, honey, 500VA is equal to 500 watts. VA stands for volt-amps, which is the apparent power in an electrical circuit, while watts are the real power. So, in this case, they're one and the same. Hope that lights up your day!


How many VA is 13A at 110v?

To calculate VA (volt-amp), you can use the formula: VA = Volts x Amps. So, for 13A at 110V, the VA would be 1430 VA.


How many watts is 60va eqal to?

The relationship between volt-amperes (VA) and watts (W) depends on the power factor of the system. For purely resistive loads, 60 VA is equal to 60 watts. However, if the load has a power factor less than 1 (common in inductive loads), the actual wattage will be less than 60 watts. To convert VA to watts, you can use the formula: Watts = VA × Power Factor.
