Question

What happens when capacitor is connected in series in colpits oscillator

Answer 1

Colpitts Oscillator Circuit. ... The capacitorCe connected in the circuit which is parallelto the Re, provides low reactive path to the amplified AC signal acting as Bypasscapacitor. The Resistors R1 and R2 form voltage divider for circuit and provides bias to the transistor.

Answer 2

What happens when capacitor is connected in series in colpits oscillator?

The frequency of the oscillations are determined by the value of the capacitors and inductor in the tank circuit.

Thus the main difference between a Colpitts Oscillator and a Hartley Oscillator is that the former uses tapped capacitance, while the latter uses tapped inductance.
