The frequency of oscillation of current in the indcutor is

Text Solution

Verified by Experts

In this ac circuit e = e_(0)sint is applied across an inductance and capacitance in parallel, current in inductance will lag the applied voltage while across the capacitor will lead,
and so` I__(L)=(V)/(X_(L)) sin(0megat+((pi)/(2)= 0.8 cosomegat`
`I_(C) = (V)/(X_(L)sin(omegat+(pi)/(2)) = 0.6 cos omegat`
So the current drawn from the source,` `I=I_(L) +I_(c) =-2 cos omegat, i.e., |I_(0) = 0.2 A`
