Audio power amplifiers usually separate the last inductor in the output stage transmission chain. The last inductor usually receives the most attention when it comes to power efficiency in a circuit.
Since circuits experience opposition to current, especially where current is changing direction, capacitive reactance or opposition needs to be balanced with inductive reactance. This is done with the help of an output inductor for maximum output to be reached.
Output inductors are used to dampen circuit resonance with the help of a shunt resistor. This is especially important in high frequency circuits where stability is a real issue.

How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
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
What is effect on amplitude shift keying modulation and demodulation due to use of transistor SL100?
The SL100 is a PNP medium power transistor, suitable for use up to ~100MHz. This can be used in the power amplifier stage, with the output connected to a tuning network/transformer + antenna for AM modulation. It's purpose, if used in this application, is to supply current (usually a voltage amplifier circuit will precede this one) to drive the antenna.
What are the uses of transistor in circuits?
Basically each and every amplifier circuit is made up of coupling or use of transistors. The amplifier amplifies the signals because transistor makes either voltage or current to rise as a result of either of it's regions of operation i.e. open circuit(cut off region) or short circuit (saturation region) Both the operation regions are not required continuously. Hecne the transistor works in either saturation or cut off regions only when emitter-base junction is forward biased, which can be applied as per requirement. APPLICATIONS OF TRANSISTOR AND HENCE AMPLIFIERS ARE : OSCILLATORS, LOUD-SPEAKERS, POWER AMPLIFIERS, VOLTAGE AMPLIFIERS, CURRENT AMPLIFIERS, ANALOG TO DIGITAL CONVERTER, DIGITAL TO ANALOG CONVERTERS
What is difference between transistor and amplifier?
A transistor is an electronic component. By itself it has little use. An amplifier is a complete, functional circuit, generally made up of several components. A transistor can be a component part of an amplifier, however an amplifier may be constructed without any transistors (using vacuum tubes instead, for instance).
What type of transistor is used in amplifier?
Depends on the type of amplifier. There are a lot of different circuits of amplifiers and each one of them use proper transistors, that works better for that circuit. Moreover, on every stage of the amplifier are used different transistors as well.
Why use a npn transistor in a common emitter bjt single stage amplifier circuit?
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.

Why transistor burns?
If inceres the base voltage of transistor them it may be burn . The base volt may be 0.8v to 1.8 If it use as a amplifier
What is the typical use of a transistor in an analog circuit?

What is the use of transistor in water level indicator?
It is used to amplify the current. The common-emiiter amplifier is designed so that a small change in voltage (Vin) changes the small current through the base of the transistor; the transistor's current amplification combined with the properties of the circuit mean that small swings in Vin produce large changes in Vout. Various configurations of single transistor amplifier are possible, with some providing current gain, some voltage gain, and some both.
