The DC voltage for the amplifier (transistor or FET) runs for a series-fed oscillator through the inductance of the LC circuit. A shunt-fed oscillator uses a radio-frequency choke or a resistor to deliver DC voltage to the amplifier. For an oscillator the difference between serial-fed and shunt-fed is small. The choke resonance frequency can interact with the LC circuit resonance frequency. This problem happens only with shunt-fed. Furthermore series-fed needs less components. Therefore it is prefered for (low power) oscillators.
The output circuit of an amp can be series-fed or shunt-fed, too. The additional DC current through the coil will drive a iron or ferrite core earlier into saturation. This is an disadvantage of serial-fed. At a high-voltage tube RF amp with say 2000V DC voltage, in the shunt-fed amp only the choke and the DC blocking capacity have to withstand the high voltage. This is an advantage of the shunt-fed solution.
In a series-fed Hartley oscillator, the coil is in series with the tank circuit, while in a shunt-fed Hartley oscillator, the coil is connected in parallel to the tank circuit. This difference affects the impedance matching and frequency stability of the oscillator circuit. Series-fed tends to have better stability, while shunt-fed may be simpler to design.

What is meant by tank circuit in hartley oscillator?
A tank circuit in a Hartley oscillator is a combination of inductors and capacitors that forms a resonant circuit. This tank circuit determines the frequency of oscillation in the Hartley oscillator by creating a positive feedback loop through the inductive and capacitive elements. The resonant frequency of the tank circuit is used to produce a stable oscillation in the Hartley oscillator circuit.
What is the difference between colpitts and clapp oscillator?
The Clapp oscillator is a variation of the Colpitts oscillator that includes an additional capacitor in series with the inductor to improve frequency stability. This additional capacitor in the Clapp oscillator helps reduce the effect of the active device's parasitic capacitance, leading to better frequency stability compared to the Colpitts oscillator.
What is the difference between hooking up a 1.5v batteries in parallel and in series?
Connecting batteries in parallel increases the capacity (runtime) while maintaining the same voltage. Connecting batteries in series increases the voltage while maintaining the same capacity. Essentially, parallel increases energy storage, while series increases voltage output.
What is inside a clock?
Inside a clock, you will typically find gears, springs, and a pendulum or oscillator that work together to accurately measure the passage of time. These components are powered by a battery or by winding the clock manually to keep it running smoothly and telling time accurately.
Why does the potential difference change in a series circuit?
In a series circuit, the total potential difference provided by the power source is divided among the components in the circuit. As current flows through each component, there is a voltage drop across each one. This results in a reduction of potential difference as you move along the circuit.
What is the difference between colpitts and hartley ossilator?
colpitts oscillator has two coils in series and one capacitor in parallel. hartley oscillator has one capacitor and one coil in parallel

What is ocillating?
In electronics, it is a circuit which repetitively produces a certain output. This may be a series of pulses or a repetitive waveform such as sine, sawtooth or ramp. In mechanics, a pendelum is an oscillator. An oscillator is the series and parallel combination of resistors and capacitors.

What is the purpose of an oscillator crystal?
"A circuit within a computer that creates a series of pulses that pace the computer's electronic system. The oscillator clock synchronizes, paces and coordinates the operations of the computer's circuit." -- webopedia
What is the common difference?

How does a Colpitts oscillator work?
A Colpitts oscillator is the electrical dual of a Hartley oscillator. In the Colpitts circuit, two capacitors and one inductor determine the frequency of oscillation. The feedback needed for oscillation is taken from a voltage divider made by the two capacitors, where in the Hartley circuit the feedback is taken from a voltage divider made by two inductors (or a tapped single inductor). (Note: the capacitor can be a variable device by using a varactor). Oscillation frequency The ideal frequency of oscillation for the circuit is given by the equation: where the series combination of C1 and C2 creates the effective capacitance of the LC tank. Real circuits will oscillate at a slightly lower frequency due to junction capacitances of the transistor and possibly other stray capacitances
