What’s the voltage of a battery in a circuit with resistance of 3 ohms and current of 5 amps?
alexira [117]

Answer: The correct answer is-15 Volts.

Explanation-

Voltage of a battery can be defined as the difference in electric potential that lies between the positive and negative terminals of a battery.

It can be calculated using Ohm's law, which states that the electric potential difference between two points on a circuit is equal to the product of the current that flows between the two points (I) and the total resistance that sis present between the two points. It can be mathematically depicted as-

ΔV = I • R  

Putting the value of 'I' and 'R', we get-

ΔV = 5 X 3

    =  15 V
