Question

A 1 pF capacitor is connected in parallel with a 2 pF capacitor, the parallel combination
then being connected in series with a 3 pF capacitor. The resulting combination is then
connected across a battery.

    Answer:

    a)3pF  has the greatest charge

    b) 3pF to have the greatest voltage.

    Explanation:

    From the question we are told that:

    1pF is parallel to 2pF =1pF//2pF

    And 3pF is in with series 1pF is parallel to2pF =3pF+(1pF//2pF)

    Generally the equation for Resultant capacitor is mathematically given by

    C=3pF+(1pF//2pF)

    C=\frac{3}{2}pF

    Ohm’s law

    Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points

    a)

    Since

    The same charge flowing through 1pF//2pF flow through 3pF

    Therefore

    3pF  has the greatest charge

    b)

    Voltage drop in series according to ohms law

    Therefore the parallel share same voltage

    Given

    3pF to have the greatest voltage.
