  • The device that stores electrical energy in an electric field is called a capacitor.
  • The capacity of a capacitor to store electric charge is called capacitance.
  • Capacitor in series combination:

    • When two or more capacitors are connected in series then they will have the same electric charge on each and hence same current will flow through them. 
    • The voltage across each capacitor is dependent on the capacitor value. 

    Capacitors in parallel combination:

    • The charge of each capacitor is different and the current flowing through each capacitor in the given time are also different and depend on the value of the capacitor.
    • The voltage across each capacitor is the same.
