(i) What values did the students have?

(ii) What energy is stored in the capacitor?

(iii) On what factors, does the capacitance of a capacitor depend?

Answer:

62.5 rad/s, 12.5 Or 184.6 V, 76.9 V

(i) Team work, concern, respect to the professor and responsibility.

(ii) A capacitor stores energy in the form of electrical potential energy.

(iii) The capacitance of a capacitor depends on the geometry of plates, distance between them and the nature of dielectric medium between them.
