Answer / ashok
No current will flow, as capacitor behaves as a open circuit
to dc supply.

Answer / s.bharathi.1991
if the d.c passes through the capacitor ,it would offers
infinite resistance to ac because the capacitive reactance
for d.c is given by
xc=1/(2*3.14*f*C)
where,
c-capacitance
f-frequency
since for d.c the frequency is 0,xc=infinity.hence no
current flows through capacitor

what is a diffrence between MCCB, RCCB, MCB, & ELCB ? what is rated current e.g. on motor name plate indicated that is rated curent? what is full load current? If we run D.C. motor with mechanical coupling and we measure voltage on terminal it shows voltage or not ? same in AC also possible ?
