Practical Examples of Usage

Example 1: Finding Power Consumption

Suppose you have a device running at:

  • Voltage = 220V
  • Current = 2A

Using the calculator:

  • Power = 220 × 2 = 440 Watts

This helps you understand how much electricity the device consumes.


Example 2: Calculating Required Voltage

Imagine you know:

  • Power = 1000W
  • Current = 5A

Using the formula:

  • Voltage = 1000 ÷ 5 = 200 Volts

This is useful for designing electrical circuits or selecting power supplies.


Example 3: Determining Current Usage

If:

  • Power = 600W
  • Voltage = 120V

Then:

  • Current = 600 ÷ 120 = 5 Amps

This helps in selecting proper wires and safety components.
