A current source of

10\,\text{A}

feeds two resistors

4\,\Omega

and

6\,\Omega

connected in parallel. When a third resistor

R

is connected in parallel, the current through the

4\,\Omega

resistor drops from

6\,\text{A}

4\,\text{A}

. Calculate the value of

R

. (a)

5.6\,\Omega

(b)

4.8\,\Omega

(c)

4.0\,\Omega

(d)

8.0\,\Omega
