How do you convert kVA to kilowatts in a resistive load?

To convert kVA (kilovolt-amperes) to kilowatts (kW) in a resistive load, you multiply the value in kVA by the power factor. The power factor represents the efficiency of the electrical system, defining the ratio of real power (used for work) to apparent power (total power in the circuit).

In a resistive load, the power factor is typically close to 1 (or 100%), because all the power supplied is effectively used to perform work, with minimal losses due to reactive components. Therefore, when converting kVA to kW in a resistive application, multiplying by the power factor provides the precise value of power being utilized by the load.

For instance, if you have a resistive load rated at 10 kVA with a power factor of 1, the calculation for kilowatts would be 10 kVA * 1 = 10 kW. This straightforward calculation demonstrates how the complete apparent power usage translates into effective power used by the load.
