what is use of capacitor in pcb circuits which work on dc but
capacitor blocks dc..?
Answer Posted / irayya mathad
by the formula of capacitor we can conclude that first we known
the formula of capacitance : 1/(2 pai f c) if in case the
capacitor connect to AC it has frequency of 50Hz, a little bit
capacitance offers to ac so it allows to Ac.In case of DC it
does not has frequency it means zero frequency then
automatically the infinite capacitance offers to DC so the
capacitor blocks the DC....
