The difference between an RC and LC is that the frequency - determining device in the RC oscillator is not a tank circuit. LC can operate with A or C biasing, while RC can only operate with A.
LC means coil capacitance circuit RC means resistance capacitance circuit
At high frequencies for rc oscillators stray capacitances comes into act so q value reduses where for lc circutes q value is high
RC COUPLING :- is the most Commonly used Coupling Between the two stages of a cascaded or multistage amplifier because it is cheaper in cost and Very compact circuit and provides excellent frequency response. TRANSFORMER COUPLING :- Impedence Coupling results in more efficient amplification because no signal power is wasted in Inductor L. Such Coupling has the drawback of being larger, Heavier and Costlier than the RC COUPLING. Impedence Coupling is rarely used beyond audio range . by : Muhammad zubair.... muet student of telecom.
No. Capacitance is determined by the area of overlap of its plates, the distance between them, and the absolute permittivity of its dielectric.
The RC circuit can reduce the phase shift between the voltage and current in the power line. The phase shift is caused by the inductance of the motor. The phase shift between the voltage and current in the power line causes problems due to the presence of so called imaginary current or power that does no work but must be supplied by the power source.

DISADVANTAGES OF RC PHASE SHIFT OSCILLATOR.1. The output is small due to smaller feedback. 2. It is difficult for the Circuit to start oscillations.3. The Frequency stability is not so Good.4. It requires high Vcc. For large feedback.
Rc phase shift uses negative feedback.. Weinbridge uses both +ve and -ve feedback
Because an RC oscillator is affected by stray capacitance in the active components in the circuit. HF oscillators use an LC tuned circuit to define the frequency.
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network

no
The name for an RC network is an oscillator.
phaseshift of wienbridge is 0
