    a) the greatest charge will be on C3=3 mF

    b) Voltage will be same across each capacitors

    Explanation:

    Given: C1 = 1 mF, C2 = 2 mF, C3 = 3 mf and V = 9 volts

    To Find: greatest charge Q=? and which capacitor has the greatest voltage=?

    Solution:

    a)

    As the voltage across each will be same so (using Q = C V)

    Q1 = 1 mF * V

    Q2 = 2 mF * V

    Q3 = 3 mF * V

    so the greatest charge will be on C3=3 mF

    b) Voltage will be same across each capacitors

    a) the 3mf capacitor has the greatest charge.

    b) they all have equal voltage which is 9V

    Explanation:

    a) the charge on a capacitor is the product of the capacitance and the voltage across the capacitor. It can be written as;

    Q = CV

    And since they are connected in parallel, the voltage across each capacitor will be the same and equal to 9V

    V1 = V2 = V3 = 9V

    So,

    For capacitors

    Q1 = 1mF * 9V = 9mC

    Q2 = 2mF * 9V = 18mC

    Q3 = 3mF * 9V = 27mC

    Therefore, the 3mF capacitor have the highest charge.

    b) Since it is a parallel connection, the voltage across each capacitor is the same and equal to 9V.
