1 BME 311 Network Theory John X.J. Zhang, UT Austin 1 Chapter 6 • Capacitor – Definition – Energy, power – Series and parallel capacitors • Inductor – Definition – Series and parallel capacitors BME 311 Network Theory John X.J. Zhang, UT Austin 2 Capacitors and Inductors • Capacitor – two conducting plates separated by an insulator (or dielectric) • Capacitance C – the ratio of the charge on one plate of a capacitor to the voltage difference between the two plates , measured in farads ( F ) q = C v or C = q / v For parallel plate capacitor C = ε⋅ A / d 1 farad = 1 coulomb/volt
