About Ohm's Law
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance. This fundamental principle is expressed as:
- V = I × R (Voltage = Current × Resistance)
- I = V ÷ R (Current = Voltage ÷ Resistance)
- R = V ÷ I (Resistance = Voltage ÷ Current)
- P = V × I (Power = Voltage × Current)
Common Applications
Ohm's Law is essential for:
- Circuit design and analysis
- Power supply calculations
- Battery life estimation
- LED circuit design
- Motor control systems
