A capacitor is similar to a battery in that both store electrical energy. But a capacitor can't actually produce new electrons; it only stores them.

In this interactive tutorial students will be introduced to capacitance and the electric fields inside a capacitor. Learn what factors affect capacitance. Also learn about dielectric and how it affects capacitance.

In this interactive tutorial students will look at the energy stored in the magnetic field of an inductor. Self-inductance and mutual inductance will be distinguished and circuits with capacitors and inductors, or LC circuits will be...
