  • Two capacitors of capacities C1 and C2 are connected in series and potential difference V is applied across the combination. then the potential difference across C1 is :

    a) V C2/C1

    b) V c1 c2/ c1

    c) V c2/ c1 c2

    d)V C1/ C1 C2

    In series, the charge on each capacitor is the same.

    The charge on the first capacitor is C1V1 and the charge on the second capacitor is C2V2. Here V1 is the potential difference across the first capacitor and V2 is the potential difference across the second capacitor.

    So, C1V1 = C2V2.

    Hence, V1 = C2V2/C1. However, V1+ V2 = V. Therefore, V1 = (C2/C1)(V-V1). Solve this equation to get the value of V1.
