Problem

Two cells of emf

E_1=6\text{ V}

and

E_2=5\text{ V}

are joined in parallel with the same polarity on the same side, without any external load. If their internal resistances are

r_1=2\Omega

and

r_2=3\Omega

, respectively, then (a) Terminal potential difference across either cell is less than

5\text{ V}

. (b) Terminal potential difference across either cell is

5.6\text{ V}

. (c) Current through the cells is

0.2\text{ A}

. (d) Current through the cells is zero if

E_1=E_2
