WebCombining the elements of voltage, current, and resistance, Ohm developed the formula: Where V = Voltage in volts I = Current in amps R = Resistance in ohms This is called Ohm’s law. Let’s say, for example, that we have a circuit with the potential of 1 volt, a current of 1 amp, and resistance of 1 ohm. Using Ohm’s Law we can say: WebThe power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): The power P in watts (W) is equal to the squared voltage V in volts (V) divided by the resistance R in ohms (Ω): The power P in watts (W) is equal to the squared current I in amps (A) times the resistance R in ohms (Ω): Ohm's law calculator See also
