So, for a circuit with 5 ohms (Ω) of a resistance that needs 3 amp (A) of current to function, the voltage required would be 15V. The power dissipated by the circuit can also be found using the values in Ohm’s Law. For example, the power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A):

Watts and Ohms are units of measurement used in electrical systems. Watts measure the rate of energy conversion or transfer and is often used to quantify the output power of a system. Ohms, on the other hand, measure electrical resistance, indicating how much a device or material resists the flow of electric current.
