A battery of emf

24\,\text{V}

and internal resistance

1.0\,\Omega

is connected in series with three external resistors of

2.0\,\Omega

4.0\,\Omega

and

6.0\,\Omega

respectively. (a) Calculate the steady current in the circuit. (b) Determine the potential difference across the

4.0\,\Omega

resistor. (c) Find the electrical energy delivered by the battery in

2\,\text{min}

of operation. (d) Compute the power dissipated inside the battery itself.
