Q1. Define the term Capacitance and Inductance?
Ans. 
Capacitance is the ability of a body to store an electric charge. Inductance is the ability of a coil to store energy in a magnetic field.
• Capacitance is measured in Farads (F)

• Capacitors are used to store energy in electronic circuits

• Inductance is measured in Henrys (H)

• Inductors are used in electronic circuits to store energy in a magnetic field

• Both capacitance and inductance are important in AC circuits
