Practical Example

Let’s walk through a real-world example:

Scenario:

You have an electrical device with:

• Current: 10 Amps
• Voltage: 220 Volts
• Power Factor: 1
• Phase Type: Single Phase

Calculation:

• Power (Watts) = 220 × 10 × 1 = 2200 W
• Power (kW) = 2200 ÷ 1000 = 2.2 kW

Result:

• 2200 Watts
• 2.2 Kilowatts

This helps you understand how much power the device consumes and whether your system can handle the load.
