Transients in Alternating-Current Circuits

Author: E.E. Kimberly

Transient currents and voltages are likely to occur in circuits when those circuits are suddenly connected to or disconnected from a source of alternating voltage. The transients are caused by the inductance and capacitance of the circuit and are mitigated by the resistance of the circuit in much the same manner as in the direct-current circuit. It will be assumed in all cases, unless otherwise stated, that the applied voltage is sinusoidal and that the impedances of all circuit elements are constant.
