Electric Circuit Analysis: Unit III: Transient Response Analysis

Transients

If a circuit containing one or more energy - storage elements (such as L and C) is excited by a source which abruptly changes its value, the energy state of the circuit is disturbed.

TRANSIENTS

If a circuit containing one or more energy - storage elements (such as L and C) is excited by a source which abruptly changes its value, the energy state of the circuit is disturbed. This disturbance may also be due to changes of L or C or both and also due to switching conditions. After a certain time the circuit settles down to a new steady state operation and the node voltage and element currents reach their final steady state values. The time required for the network to change from one steady state to another steady state is called transient period. The values of voltages and currents during the transient period are known as transient responses or simply transients. Transient means short lived. In electrical circuit transients do not occur if it is purely resistive. For the transients to take place there must be presence of L or C or both in the circuit.
