Question

A motor with an operating resistance of 24Ω is connected in a circuit witn 0.4A of current. The battery voltage must be volts

Answer 1

Voltage = 9.6 Volts

Step-by-step explanation:

Given the following data;

Resistance = 24Ω

Current = 0.4A

To find the voltage of the battery;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

`V = current * resistance`

Substituting into the formula, we have;

Voltage = 0.4 * 24

Voltage = 9.6 Volts

Therefore, the battery voltage must be 9.6 volts
