Practical Example

Scenario: A 240V AC circuit carries 10A with a power factor of 0.9.

Inputs:

  • Voltage: 240V
  • Current: 10A
  • Power Factor: 0.9
  • Circuit Type: AC

Output Using Kilowatt Calculator:

  • Power: P=V×I×PF=240×10×0.9=2,160W=2.16 kWP = V \times I \times PF = 240 \times 10 \times 0.9 = 2,160 \text{W} = 2.16 \text{ kW}P=V×I×PF=240×10×0.9=2,160W=2.16 kW

This allows electricians and homeowners to understand real power usage and plan accordingly.
