A resistance of 60Ω has a current of 0.73A through it when it is connected to the terminals of a battery. The voltage of the battery is V. (Just write the number.

43.8 Volts

Explanation:

Ohms law states that current is directly proportional to voltage applied.

where V = voltage = ?

I = current = 0.73 A

R = resistance = 60 ohm

Putting in the values we get:

Thus the voltage of the battery is 43.8 Volts
