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.


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.


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.

Is walking a in-phase oscillation or out of phase oscillation?

Walking is a form of out-of-phase oscillation, where the motion of the legs alternates with each step. This creates a continuous and coordinated pattern of movement necessary for walking.


What is the time period of each oscillation?

The time period of each oscillation is the time taken for one complete cycle of the oscillation to occur. It is typically denoted as T and is measured in seconds. The time period depends on the frequency of the oscillation, with the relationship T = 1/f, where f is the frequency of the oscillation in hertz.


What are the terms of free oscillations?

If a circuit is unstable and oscillates then the term free oscillation can be applied.


What is the time that it takes a complete cycle or wave oscillation to occur is called?

The time it takes for a complete cycle or wave oscillation to occur is called the period. It is usually measured in seconds and is inversely proportional to the frequency of the wave.


How do you calculate the period T of an oscillation?

The period of an oscillation can be calculated using the formula T = 1/f, where T is the period and f is the frequency of the oscillation. The frequency is the number of complete oscillations that occur in one second.


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 meant by tank circuit in hartley oscillator?

it is the circuit that is responsible for producing oscillation.In hartley it is two inductors connected in series and a capacitor parallel to this series connection.Without tank oscillator tends to act as as an amplifier.


What 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 type of feedback used in the oscillator circuit?

There are many different types of oscillator circuits, the majority of which use positive feedback.
