Problem

Two resistors of

8\,\Omega

and

12\,\Omega

are connected in parallel to a

24\,\text{V}

source. A fuse rated at

4\,\text{A}

is placed in series with the

8\,\Omega

branch. What will happen to the fuse when the circuit is switched on? (a) Fuse will melt; current is

5\,\text{A}

(b) Fuse will melt; current is

3\,\text{A}

3\,\text{A}

(d) Fuse will not melt; current is

2\,\text{A}
