Learning Goals - we will learn: Ch 24 • The nature of capacitors , and how to calculate their ability to store charge . • How to analyze capacitors connected in a network. • How to calculate the amount of energy stored in a capacitor. • What dielectrics are, and how they make capacitors more effective.

Any two conductors insulated from one another form a CAPACITOR . A "charged" capacitor can store charge. When a capacitor is being charged, negative charge is removed from one side of the capacitor and placed onto the other, leaving one side with a negative charge (- q) and the other side with a positive charge (+q).
