for high frequency applications(RF oscillator) we use BF 194
transistor has 2 output 1 and 0 so can be used as a switch
Its a Transistor used in JFET (Junction Field Effect Transistor)
Yes, a transistor can amplifiy an a.c. signal.
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
The BF194 is a low-noise N-channel MOSFET transistor commonly used in RF amplification applications. It features a high input impedance, making it suitable for sensitive electronic circuits. This transistor is often utilized in communication devices and signal processing due to its ability to operate efficiently at high frequencies. Its compact size and performance characteristics make it a popular choice in various electronic designs.

A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
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
MOSFET
A cross coupled transistor pair are used to increase the gain of the cell.
The metalloids is combined in transistor radios to make them of high quality.
