Transistor as an Amplifier – Circuit Diagram, and Its Working
The input of the amplifier is a voltage otherwise current, where the output will be an amplifier input signal. An amplifier circuit which uses a transistor otherwise transistors is known as a transistor amplifier. The applications of transistor amplifier circuits mainly involve in audio, radio, optical fiber communication, etc.
Electronics Components: Use a Transistor as a Switch
This is a schematic diagram for a circuit that uses an NPN transistor as a switch that turns an LED on or off. Look at this circuit component by component: LED: This is a standard 5 mm red LED. This type of LED has a voltage drop of 1.8 V and is rated at a maximum current of 20 mA. R1: This 330 ω resistor..

This circuit is built around just two transistors as the main active components. The configuration is in the form of a standard Darlington pair, which increases its current amplification capacity hugely. Rain drops or water drops falling and bridging the base with the positive supply is enough to trigger the alarm.
All about 2n2222 transistor and its Circuit diagrams
Circuit Diagram: The circuit has only one transistor with a relay as load at its collector. A current limiting resistor R 2 is connected across the positive supply rail and base of the transistor along with five switches (S0 to S4) in series. Other five parallel arranged switches (S5 to S9) are connected between transistor’s base and ground.
How Transistors Work - A Simple Explanation
May 28, 2014A 9V battery connects to an LED and a resistor. But it connects through the transistor. This means that no current will flow in that part of the circuit until the transistor turns ON. To turn the transistor ON you need to apply 0 from base to emitter of the transistor
NPN Transistor Circuit Working, Characteristics, Applications
Jan 23, 2015NPN Transistor Circuit The above figure shows the NPN transistor circuit with supply voltages and resistive loads. Here the collector terminal always connected to the positive voltage, the emitter terminal connected to the negative supply and the base terminal controls the ON/OFF states of transistor depending on the voltage applied to it.
NPN Transistor - Circuit Globe
Circuit Diagram of NPN Transistor. The circuit diagram of the NPN transistor is shown in the figure below. The collector and the base circuit is connected in reverse biased while the emitter and base circuit is connected in forward biased. The collector is always connected to the positive supply, and the base is in negative supply for controlling the ON/OFF states of the transistor. Working of NPN

Transistor amplifier circuits
Mar 14, 2011Description. This is the circuit diagram of a Headphone amplifier operating in the class A push pull mode. In class A mode the output device (transistors) conduct over the entire input signal cycle. The maximum possible efficiency for Class A operation is 50% and it further reduces when capacitive coupling is used.
