It is not "necessary" for oscillation to occur in any "arbitrary" circuit. It depends on the design objectives. Please be more specific, and restate the question.

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
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
Why the carrier for the amplitude modulation must be a sinusoidal waveform?
The wave in amplitude modulation must be a sine wave. A sine wave represents smooth repetitive oscillation, which is necessary for this process.
When will a negative feedback amplifier circuit be unstable?
It will oscillate if the loop gain exceeds 1 when the phase difference round the loop is 360 degrees. The frequency of oscillation is set by the loop phase being equal to 360 degrees.
Can a circuit breaker be locked in the on position to stop inadvertent switch offs?
No, this isn't necessary. The circuit breaker protects your home by avoiding an overcharging caused by a short-circuit. It's advisable blocking the access to the breaker.
What are the terms of free oscillations?
If a circuit is unstable and oscillates then the term free oscillation can be applied.
What makes oscillation happen?
Oscillation can occur in any body of water where gentle waves barely touch the bottom or where weak currents move back and forth in shallow water.
Where does resonance occur?
Resonance can occur in any solid material where the frequency of oscillation in the material is equal to the natural frequency of the material.
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
What is resonant cicuit?
An electrical circuit that combines capacitance and inductance in such a way that a periodic electric oscillation will reach maximum amplitude
What are the condition for oscillation?
There are three conditions. These include positive feedback, the phase near the circuit needs to be either 36 or zero degrees, and the loop gain should be equal or greater than 1.
What city do el nino occur in?
El Nino is a coupled ocean-atmosphere oscillation. It has effects on most cities in the world.

Why the fuse wire necessary in a circuit?
It is a safety device. It is not an essential part of the circuit.
What is necessary for photosythesis to occur?
Water, sunlight, carbon dioxide and chlorophyll are necessary for photosynthesis to occur.
Is walking a in-phase oscillation or out of phase oscillation?
out
When did la Nina and el nino occur at same time?
It is impossible for them to occur at the same time. They are two opposite phases of the same oscillation. It is either one or the other, or it is somewhere in between (neutral).
