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.
