Equation for resistance current and voltage
WebVoltage, Current, Resistance Ohm’s Law relates voltage, current, and resistance. It is represented by a simple equation. V = I * R V = voltage (volts) I = current (amps) R = resistance (ohms) If you keep the resistance the same and increase the voltage, the current has to increase. WebThe electrical resistance of a circuit is the ratio between the voltage applied to the current flowing through it. Rearranging the above relation, R = V I. The unit of electrical resistance is ohms. o h m = 1 v o l t 1 a m p …
