Power Calculation
Power (P) can be calculated as P = V×I, P = I²R, or P = V²/R.
FAQs
What is Ohm's Law?
Ohm's Law states that voltage (V) = current (I) × resistance (R). It's fundamental for circuit design.
How do I calculate power?
Power = Voltage × Current (P = V × I). Power is measured in watts (W).
What units are used?
Voltage in volts (V), current in amperes (A), resistance in ohms (Ω), power in watts (W).
