Webb26 jan. 2024 · Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them. The mathematical equation that describes this relationship is: I = V/R
WebbOhms Law Example No1 For the circuit shown below find the Voltage (V), the Current (I), the Resistance (R) and the Power (P). Voltage [ V = I x R ] = 2 x 12Ω = 24V Current [ I = V ÷ R ] = 24 ÷ 12Ω = 2A Resistance [ R = V ÷ I ] = 24 ÷ 2 = 12 Ω Power [ P = V x I ] = 24 x 2 = 48W WebbSome students have trouble memorizing the formula even if they are quite simple.
