📌 Practical Examples of Usage
Example 1: Calculating Power at Home
Suppose you have a device that uses:
- Voltage = 220V
- Current = 2A
Using the formula:
P = V × I = 220 × 2 = 440W
This helps you understand how much electricity your appliance consumes.
Example 2: Finding Voltage for a Circuit
You know:
- Power = 1000W
- Current = 5A
Formula:
V = P ÷ I = 1000 ÷ 5 = 200V
This is useful when selecting compatible power sources.
Example 3: Determining Current Usage
If:
- Power = 600W
- Voltage = 120V
Then:
I = P ÷ V = 600 ÷ 120 = 5A
This helps in choosing correct wiring or circuit protection.
