A sinusoidal voltage of 10 sin 100t is connected in series with a
switch and R=10 Ω, L=0.1H. If the switch is closed at t=0,
determine the transient current i(t).
Answers
The transient current is 10cos100t.
Given:
voltage = 10 sin 100t
R=10 Ω
L=0.1H
To find : transient current i(t)
Solution:
Electrical transient are brief bursts of strength persuaded upon power, dossier, or ideas lines. They are from intensely extreme voltages that drive overwhelming amounts of current into an electrical track for any millionths, until any thousandths, of a second. Large transient on the capacity order originating except for a convenience are best originally deflected at the aid entrance of a ease.
Transients generated inside the homes are best deflected by SPDs situated nearly the within source of the transient or nearly the photoelectric load supplies if this is not attainable. Best results are acquired if two together locations are shielded.
Lets calculate it through formula,
V=L dt*di i= L1
∫100sin(100t)dt
i=−10cos100t
Therefore the current is 10cos100t .
