astable multivibrator type transistor is free running oscillator.so it has greater stablity . it can be varied by resistor and capacitor value
A: A circuit to be useful to do work must be stable with the environment and also with reliable circuit performance. A circuit that is allow break into oscillation or other criteria is not stable therefore not much useful.
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
a transistor circuit for driving the coil of a magnetic relay.
Transistor are DC output, Triac are AC output.
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
This mechanism is how a transistor works.
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
A switch, switching transistor, or circuit breaker usually does.
Selection and setting of a transistor's operating pointto meet circuit functional requirements.
the base circuit
amplification
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
