Find the total current drawn from the battery as shown in the circuit diagram :
Answer & explanation
Correct answer: option 1
This circuit is balanced wheat stone bridge. Hence $50\Omega$ resistors can be removed from the circuit. 3 , $10\Omega$ resistor are in series . Two $30\Omega$ resistor are in parallel.
Equivalent resistance is $15\Omega$.
$ I = \frac{6}{3+15} =\frac{1}{3} = 0.33A$
