Chapter 7: Response of First-Order RL and RC Circuits

RL Circuit

A  first-order circuit that consists of a resistor and an inductor

RC Circuit

A first-order circuit that consists of a resistor and a capacitor

Natural Response

the response of the circuit where the nature of the circuit itself, not external sources of excitation, determines its behavior.

Step Response

The response of a circuit to the sudden application of a constant voltage or current source

First-Order Circuits

circuits whose voltages and currents are described by first-order differential equations.

Transient Response

momentary events that occur after switching where there are changes in current and voltage

Steady-State Response:

the response that exists a long time after switching

Sequential Switching

whenever switching occurs at two or more distinct times in a circuit. is analyzed in first-order circuits by dividing the analysis into time intervals corresponding to specific switch positions. Initial values for a particular interval are determined from the solution corresponding to the immediately preceding interval

Unbounded Response

a circuit response that grows rather than decays exponentially with time. Occurs when the Thévenin resistance is negative, which is possible when the first- order circuit contains a dependent source

Integrating Amplifier

a circuit that generates an output voltage proportional to the integral of the input voltage
