If the battery voltage in the given balanced Wheatstone bridge circuit is $12 \mathrm{~V}$, the current passing through the battery is

Professor PC Thomas Classes · Answer

(a) : The circuit forms a balanced Wheatstone bridge, which means the resistance in the central arm can be ignored. Based on the original structure, the equivalent resistance of the outer branches remains $R_{eq} = 10 \Omega$. When the battery voltage is increased to $V = 12 \mathrm{~V}$, the new current drawn from the battery is $I = \frac{V}{R_{eq}} = \frac{12}{10} = 1.2 \mathrm{~A}$.
