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 / varunkumar_89
See,the open circuit does mean voltage = 0. It means current =0. The reverse is true for short circuit situation. At low frequencies the capacetive reactance becomes high, the there is lesser current flowing through capacitor. Hence there is more voltage drop across it. Thus the all input appears across capacitor. When frequency is zero (DC signal), there is almost zero current through capacitor. Hence maximum voltage is present across it. So we get the output.
