⚡ Formula
V = I × R
Ohm’s Law states that voltage is equal to current multiplied by resistance.
🔧 Explanation
- Voltage (V) → Electrical pressure
- Current (I) → Flow of electricity
- Resistance (R) → Opposition to current
🧪 Uses
- Calculate voltage, current, resistance
- Design electrical circuits
- Troubleshoot problems
⚙️ Applications
Home Wiring
Used to design safe electrical systems in houses.
Electronics
Used in mobile phones, laptops and TVs.
Battery Systems
Helps calculate power and current flow.
Automobiles
Used in car wiring and lighting systems.
⭐ Importance
- Foundation of electrical engineering
- Ensures safety
- Used in every electronic device
🧠 Example
If Voltage = 10V and Resistance = 5Ω
Current = 2A
