If we connect capacitor in series DC supply so what happened?
Answer Posted / 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
