We will study capacitors and inductors using differential equations and Fourier analysis and from these derive their impedance. Capacitors and inductors are used primarily in circuits involving time-dependent voltages and currents, such as AC circuits. Most electronic circuits involve time-dependent voltages and currents.
When a capacitor is included in a circuit, the current will change with time, as the capacitor charges or discharges. The circuit shown in Figure 20.5.1 shows an ideal battery 1 ( ΔV ), in series with a resistor ( R ), a capacitor ( C, two vertical bars) and a switch ( S) that is open.
The basic capacitor consists of two conducting plates separated by an insulator, or dielectric. This material can be air or made from a variety of different materials such as plastics and ceramics. This is depicted in Figure 8.2.2 . Figure 8.2.2 : Components of a generic capacitor.
This action is not available. Introducing when a circuit has capacitors and inductors other than resistors and sources, the impedance concept will be applied. Let's consider a circuit having something other than resistors and sources. Because of KVL, we know that: vin = vR +vout v i n = v R + v o u t The current through the capacitor is given by:
Therefore we can state a particularly important characteristic of capacitors: The voltage across a capacitor cannot change instantaneously. (8.2.7) (8.2.7) The voltage across a capacitor cannot change instantaneously. This observation will be key to understanding the operation of capacitors in DC circuits.
We now use the above concepts to analyze simple AC circuits using complex numbers. where V0 is a real number equal to the peak voltage and ω = 2πf is also a real number with f the frequency of the voltage source. Let us consider a simple AC circuit with a resistor as shown below. Let v(t) be an AC voltage source given by
