we r saying that low pass rc filter will allow low frequency
components n attenuates the high frequency components..but
at low frequency reactance offer by capacitor is high..it
will act as open circuit..hence there will no output..but
practically we getting output. how?
Answer Posted / ravi shanker
At low frequency the reactance offer by capacitor is high. For dc current which frequency is zero reactance offer by capacitor is infinite. so ur statement is wrong about the reactance offer by capacitor at low frequency.
