Question No. 29-A circuit consisting of a capacitor C, a resistor of resistance R and an ideal battery of emf V, as shown in figure is known as RC series circuit. As soon as the circuit is completed by closing key S₁ (keeping S₂ open) charges begin to flow between the capacitor plates and the battery terminals. The charge on the capacitor increases and consequently the potential difference V (= q/C) across the capacitor also increases with time. When this potential difference equals the potential difference across the battery, the capacitor is fully charged (Q = VC). During this process of charging, the charge q on the capacitor changes with time t asq = Q [1 - e^-t/RC}] the charging current can be obtained by differentiating it and using d/dx(e^mx) = m e^mx | CBSE class 12 physics solution by ujwal Kumar physics master | physics master academy is best coaching for all physics students. | ujwal kumar
