Question 21: Current Electricity

Question

In the circuit shown, if the 10 $$\Omega$$ resistor is replaced by a resistor of 15 $$\Omega$$, then what is the amount of current drawn from the battery?

Accepted Answer

From the following circuit diagram, $${{{R_1}} \over {{R_3}}} = {{{R_2}} \over {{R_4}}}$$, so the given Wheatstone bridge is balanced.
Hence, there is no current in the wire of 10 $$\Omega$$ resistance.
As,
Now, if the 10 $$\Omega$$ wire is replaced with 15 $$\Omega$$ wire, the bridge still remains balanced. Hence, current drawn from battery will be 10A.
