📌 Practical Examples of Using the Calculator
Example 1: Home Appliance Power Check
You have a fan that uses:
- Voltage: 220V
- Current: 0.5A
Using the calculator:
- Watts = 220 × 0.5 = 110W
👉 This helps you understand electricity consumption and estimate your monthly bill.
Example 2: Solar Panel System Setup
You are designing a solar system and know:
- Power: 300W
- Current: 10A
To find voltage:
- Volts = 300 ÷ 10 = 30V
👉 This helps in selecting compatible batteries and inverters.
Example 3: Phone Charger Safety Check
A charger outputs:
- Power: 18W
- Voltage: 9V
To find current:
- Amps = 18 ÷ 9 = 2A
👉 This helps ensure your charger is safe and compatible with your device.
