Answer:
Correct Answer: 50.(d)
Solution:
Formula:
- Given circuit is redrawn and can be simplified as
So, current drawn through cell is
$ \begin{aligned} i & =\frac{\text { Voltage }}{\text { Net resistance of the circuit }} \\ & =\frac{V}{R _{\text {eq }}^{\prime \prime}}=\frac{15}{(160 / 3)}=\frac{9}{32} A \end{aligned} $
