In a parallel RC circuit with a true power of 2,420 watts and an apparent power of 3,102 volt amps, what is the power factor in percent?

To determine the power factor in a parallel RC (resistor-capacitor) circuit, you need to compare the true power and the apparent power. The power factor is calculated using the formula:

Power Factor (PF) = (True Power / Apparent Power) x 100%.

In this case, the true power is 2,420 watts, and the apparent power is 3,102 volt-amps.

Using the formula:

Power Factor = (2,420 watts / 3,102 volt-amps) x 100%

Power Factor = 0.780 = 78%.

This means that the power factor is 78%. The power factor represents the efficiency of power usage in the electrical circuit and is expressed as a percentage. A higher power factor indicates a more efficient utilization of electrical power.

Choosing 78% as the power factor indicates that this is the correct calculation based on the provided true and apparent power values, correctly reflecting the relationship between these two measurements in the circuit.
