What the major components of a colpitts oscillator?
1.CE amplifier circuit 2.LC oscillator circuit
How does a transistor act as a oscillator?
A: actually any active components will oscillate with positive feedback A transistor can be used as an amplifier along with an LC tank circuit to form an oscillator; it is an active device (as LIBURNO states) which will amplify the feedback signal coming out of the LC tank circuit. The tank circuit has a natural resonant frequency, meaning the L and C together will try to generate a specific frequency; this is then fed back into the input of the transistor amplifier, and the output is fed to the LC tank circuit exacerbating this oscillation until it reaches its' maximum level. An inverting amplifier can be used similarly; the output is fed to the input; this will cause the output to change as fast as the amplifier can. The frequency of this design is much harder to control, but potentially higher. Also, without the LC tank, the output voltage will remain lower.
Why doesn't LC circuit exist?
even though a resistance is not connected in a circuit, it would practically have small resistance due to its components.so practically a LC circuit dosent exist..only a RLC circuit exists
Are LC circuits and tuned circuits same thing?
a "LC circuit at resonance" and tuned circuits are the same
When a parallel LC circuit is tuned to resonance will the current be at a maximum or a minimum?
Inside the circuit loop between the inductor and capacitor the current will be at maximum. Outside the circuit the current through the LC tank circuit will be at minimum. It depends on where you are measuring it.

Where is the LC Circuit located?
The LC circuit, or tank circuit, is most commonly located in radios. Its function is to tune radio transmitters to a specific station. The LC circuit consists of an inductor (L), and a capacitor(C), hence the term, LC circuit.
Circuit for single tuned amplifier?
A single tuned amplifier basically consists of a tuned circuit (which may consist of an IFT or a parallel tuned LC circuit) connected to the collector of an amplifier circuit (in Common Emitter configuration). The tuned circuit is designed to get a resonant frequency equal to the incoming frequency signal that arrives at the base. The Single Tuned Amplifier gives maximum amplification to that particular incoming frequency which matches the resonant frequency of the tuned circuit and attenuates all other frequencies. Thus it gives sharp selectivity with a high Q-factor.
What is the difference between LC and RC filters?
LC means coil capacitance circuit RC means resistance capacitance circuit
