Practical Example

Imagine you have an electric heater with the following specifications:

• Current: 15 A
• Voltage: 240 V
• Power Factor: 0.95

Step 1: Enter 15 in the Amps field.
Step 2: Enter 240 in the Voltage field.
Step 3: Enter 0.95 for the Power Factor.
Step 4: Click Calculate.

Result:

Watts = 15 × 240 × 0.95 = 3,420 W

This means your heater consumes 3,420 watts of power under these conditions. You can now use this information to determine the appropriate circuit rating or estimate energy costs.
