    Capacitance of each capacitor

    C1=A3ε012=6Aε0

    C2=A4ε0=4Aε0

    Equivalent capacitance

    Δv2=240Aε04Aε0=60v

    vfoil=60v

It is the farad (F). The name came from Michael Faraday. SI Unit of Capacitance means the ability of a system to store an electric charge. One farad is the capacitance of a device that needs one coulomb of charge to provide one volt potential difference across it. Mathematically, it is represented by - 1 Farad = 1 Coulomb/Volt.
