A transistor.
resistor
Voltage amplifier
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
small signal operations
Colector resistance in an emitter follower circuit serves to place a limit on how much current can be supplied by the transistor. Often, the resistor is sized so that a short circuit in the load does not cause the transistor to fail.
Is you'll need to short circuit between the drain and the source to identify FET test
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.
