Displacement current id is given by
............................(1)
where A is area of plates of capcitor , εo is permittivity of free space , d is distance between plates of capacitor
and V is rms voltage of alternating current .
if angular frquency ω of alternating current is 300 rad/s, then rms value (dV/dt) is calculated as follows
RMS vaule of (dV)/dt = 230 × 300 V/s = 69000 V/s
Capacitance C = = 200 pF
Hence by substituting capacitance and rms value of dV/dt in eqn.(1) , we get
---------------------------------------------------
RMS value of onduction current is
where z is impedence of the circuit
Conduction current = 230 / ( 1.667 × 107 ) A = 1.38 × 10-5 A
--------------------------------------
Conduction current = displacement current
