![]() ![]() (ii)The bound charges are those positive ions which are made up of the nuclei and the bound electrons remain in their fixed positions. These free electrons are free charges inside a conductor and are cause of conduct of electricity by conductors. ![]() These electrons are free for moving within the metal but not free to leave the metal. (i)In a metal, the outer (valence) electrons are free to move. So,total charge flowing in the circuit is.Ģ.Free Charges and Bound Charges inside a Conductor Explanation: As the two capacitors are in series,their equivalent capacitance is 4.7×3.34.7+3.3=1.94μF. ![]() Find the capacitance of the capacitor C 2 if area of the plates is A and distance between the plates is d. The space between its plates is now filled with slabs of dielectric constants K x and K 2 as shown in figure. NOTE Inside a conductor, the electrostatic field is zero.ġ8.You are given an air filled parallel plate capacitor C 1. Electrostatic Potential and Capacitance Important Questions for CBSE Class 12 Physics Capacitanceġ.Conductors and Insulators Conductor contains a large number of free charge carriers to conduct electricity while insulator does not contain any free charge carriers to conduct electricity.Įxamples of conductors are metals and graphite.Įxamples of insulators are plastic rod and nylon.
