Q3. What is capacitor
Ans. 
A capacitor is an electronic component that stores and releases electrical energy in a circuit.
• Capacitors consist of two conductive plates separated by an insulating material called a dielectric.

• They are used to filter out noise in electronic circuits, store energy in flash cameras, and smooth out voltage fluctuations in power supplies.

• Capacitance is measured in Farads (F) and determines how much charge a capacitor can...read more
