We know the relation between current (I), charge (Q), and time (t): \[ I = \frac{Q}{t} \] Given: Q = 6 C, t = 2 minutes = 120 seconds Substitute into the formula: \[ I = \frac{6}{120} = 0.05 \text{ A} \]
The correct option is (C): \(0.05A\)

The equivalent resistance between the points \(A\) and \(B\) in the given circuit is \[ \frac{x}{5}\,\Omega. \] Find the value of \(x\). 
A Wheatstone bridge is initially at room temperature and all arms of the bridge have same value of resistances \[ (R_1=R_2=R_3=R_4). \] When \(R_3\) resistance is heated, its resistance value increases by \(10%\). The potential difference \((V_a-V_b)\) after \(R_3\) is heated is _______ V.
