Question

how does the voltage transients occur ?what is the typical nature of the voltage generated from such noises?

Answer 1

Voltage Transients; * The voltage transients are defined as Short duration Surges or spikes of electrical energy due to sudden release of energy stored in elements like inductors or capacitors * In electronic or electrical circuits, the containing storage elements like inductor or capacitor, when switching action takes place, a short duration pulses or spikes are induced which are called voltage transients: * These voltage transients lasts for a few Micro seconds or nano seconds only.

# The response of the circuit due to these transients is called transient Response. voltage transient Voltage A >t (ms) Fig: voltaje Transients in source vo Hoge Nature of transient voltage: v ܥܬܠ ܐ 캬 Fig! Spikes * The nature of voltage transients are Short duration pulsy like Spikes with very small duration in the order of us tons.

Example .. series R-L circuit tzo R S vs Here when the switch is immediately closed at t=o the inductor becomes open circuited because it does not allow Sudden changes in Cersent. * Because of thy swittling action a transient voltage appears across the inductor
