Problem

Two resistors of

4\,\Omega

and

8\,\Omega

are connected in parallel across a

12\,\text{V}

battery. The

8\,\Omega

resistor is replaced by a

2\,\Omega

resistor while the battery voltage remains the same. What happens to the current through the

4\,\Omega

resistor? (a)

6\,\text{A}

(b)

3\,\text{A}

(c)

1.5\,\text{A}

(d)

2\,\text{A}
