📘 Practical Example 1: Home Appliance Electricity Usage
Imagine you want to calculate how much power a fan consumes.
Given:
- Voltage = 220V
- Current = 0.5A
Calculation:
Power = V × I
Power = 220 × 0.5 = 110 Watts
Result:
The fan consumes 110W of power
👉 This helps users estimate electricity usage at home and manage energy bills better.
📗 Practical Example 2: Electrical Circuit Design
An electronics student is designing a circuit and needs resistance.
Given:
- Voltage = 12V
- Current = 2A
Calculation:
Resistance = V ÷ I
Resistance = 12 ÷ 2 = 6 Ohms
Result:
The required resistance is 6Ω
👉 This is useful for circuit design, lab work, and academic assignments.
