What is the typical use of a transistor in an analog circuit?
amplification
How do you use the Transistor output terminals of an electronic counter in a Electrical control circuit?
They use transistor as the purpose to transfer the voltage
Why to use pnp transistor in fire alarm circuit?
You can use a PNP or an NPN transistor in a fire alarm circuit. Both will work. It all depends on how you want to energize the alarm, and with what polarity of signal.
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
What is transistor relay driver?
a transistor circuit for driving the coil of a magnetic relay.
What is the ac equivalent circuit for a transistor?
Transistor are DC output, Triac are AC output.
How transistor acts as a amplifier?
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
Internal circuit diagram and working principle of transistor npn sl100?
This mechanism is how a transistor works.
DC blocking in a transistor is achieved by?
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.
I am trying to make a seat belt safety light How do you add in a buzzer to an astable circuit which already has and LED?
Use the astable to switch a power transistor and connect the buzzer as the transistor load.
What part in an electric circuit opens and closes the circuit?
A switch, switching transistor, or circuit breaker usually does.
How do you define transistor biasing?
Selection and setting of a transistor's operating pointto meet circuit functional requirements.
