Electric Circuit: Find Voltage Req'd to Charge Battery

[Jabababa]

Homework Statement

A battery has an emf of 24 V and an internal resistance of 0.25 ohm is being charged at a rate of 24 A. What is the voltage required to do this?

Homework Equations

V(terminal) = emf +/- Ir

The Attempt at a Solution

Since the battery is getting charged that means we use the V= emf + Ir

V = 24 + (24)(0.25) = 30V

Is this correct?
