Flashlight has resistance of 2.4 what voltage is applied by the batteries if the current is 2.5a

6 voltage is applied by the batteries.

Explanation:

To solve this sort of problem involving current, resistance and voltage, we use the relation: Voltage = Current x Resistance.

From the problem, the following have been given:

Resistance = 2.4 ohms.

Current = 2.5 amps.

Required: Voltage?

Fix the values of current and resistance into the relation:

Voltage = 2.5 x 2.4

=6 volts.
