4\,\Omega

resistor and an

8\,\Omega

resistor are connected in series to a

24\,\text{V}

battery. The

8\,\Omega

resistor is replaced by a

12\,\Omega

resistor while the battery voltage remains the same. What is the new potential difference across the

4\,\Omega

resistor? (a)

8\,\text{V}

(b)

12\,\text{V}

(c)

6\,\text{V}

(d)

18\,\text{V}
