Introduction: Charging a Sphere; Definition of Capacitance ice for holding electrical charge. Of course, any electrically isolated macroscopic object can hold some charge, but the term capacitor is only …

Capacitors are important components of electrical circuits in many electronic devices, including pacemakers, cell phones, and computers. In this chapter, we study their properties, and, over the …

In SI units, we measure charge in Coulombs and potential in Volts, so the unit of capacitance is the Coulomb/Volt. This combination is given a special name: the Farad, or F.

The capacitance tells us what the potential di®erence between the conductors would be for a given amount of charge placed on two conductors (equal in magnitude and opposite in sign).

Goal of this chapter is to learn what is Capacitance, its role in electronic circuit, and the role of dielectrics. How to use electric potential to move opposite signed charges to two different conductors?

Electric Potential and Capacitance This chapter covers electric potential energy, electric potential, and capacitance.

The battery is disconnected once the charges Q and –Q are established on the conductors. This gives a fixed potential difference V = voltage of ab battery. Capacitance: constant equal to the ratio of the …
