D$ - 5/6\,amp$
d (d)Suppose current through different paths of the circuit is as follows.
After applying $KVL$ for loop $(1)$ and loop $(2)$
We get $28{i_1} = - 6 - 8$ $⇒$ ${i_1} = - \frac{1}{2}\,A$
and $54{i_2} = - 6 - 12$ $⇒$ ${i_2} = - \frac{1}{3}\,A$
Hence ${i_3} = {i_1} + {i_2} = - \frac{5}{6}\,A$

The current $i_1$ and $i_2$ through the resistors $R_1(=10\,\Omega )$ and ${R_2}\left( { = 30\,\Omega } \right)$ in the circuit diagram with $E_1 = 3\,V$, $E_2 = 3\,V$ and $E_3 = 2\,V$ are respectively
A current of $0.1 \,A$ flows through a $25 \,\Omega$ resistor represented by the circuit diagram. The current in $80 \,\Omega$ resistor is ........... $A$
