Question : 122 of 200

Marks: +1, -0

At time t =

0^{+}

with zero intial condition, which of the following acts as an open circuit?
i. Inductor
ii. Capacitor
iii. Resistor

Solution:

Current can not change instantaneously in an inductor.
So current at

t = o^{+}

equal to

t = o^{–}

i.e.

I(o^{–}) = I (o^{–}

) and starting current is zero the inductor behave of open circuit.
