About Ohm's Law
Ohm's Law is a fundamental principle in electrical engineering that describes the relationship between voltage (V), current (I), and resistance (R) in electrical circuits.
Key Formulas:
- • V = I × R (Voltage)
- • I = V ÷ R (Current)
- • R = V ÷ I (Resistance)
- • P = V × I (Power)
Units:
- • Voltage: Volts (V)
- • Current: Amperes (A)
- • Resistance: Ohms (Ω)
- • Power: Watts (W)
