Transients in D.C. Circuits When a circuit goes from one steady-state condition to another steady-state condition, it passes through a transient state which is of short duration. The word transient means temporary or short lived.When a d.c. voltage source is first connected to a series RC network, the charging current flows only until the capacitor is fully charged. This charging current is called a transient current. In connection with d.c. circuits, a transient is a voltage or current that changes with time for a short duration of time and remains constant thereafter. As a capacitor charges, its voltage builds up (i.e., changes) until the capacitor is fully charged and its voltage equals the source voltage. After that time, there is no further change in capacitor voltage. Thus the voltage across a capacitor during the time it is being charged is an example of a transient voltage. | |
