Frequently Asked Questions
What are the fundamental formulas of Ohm's Law?
V = I × R (Voltage = Current × Resistance), and P = V × I (Power = Voltage × Current = I² × R = V² / R).
What units are standard in Ohm's Law calculations?
Voltage is in Volts (V), Current in Amperes (A), Resistance in Ohms (Ω), and Power in Watts (W).
