Two resistors of

4\,\Omega

and

12\,\Omega

are connected in parallel across the same battery. Which statement about the currents

I_4

(through

4\,\Omega

) and

I_{12}

(through

12\,\Omega

) is correct? (a)

I_4 = I_{12}

(b)

I_{12} \text{ is three times } I_4

(c)

I_4 \text{ is three times } I_{12}

(d)

I_4 \text{ is one–third of } I_{12}
