Pnp Transistor Amplifier Circuit Diagram. The symbol and structure for pnp transistor is shown below. Below is the circuit for connecting a pnp transistor which can function as a switch or an amplifier.
Amplification can be accomplished using vacuum tubes or semiconductor devices such as transistors or integrated circuits. The amount of amplification in a circuit is known as gain the gain is the ratio between the strength of the output current voltage or wattage and the strength of the input current voltage. We used 2sc5200 and 2sa1943.
Unless it is pressed normally no current flows into the base of the transistor.
Below is the circuit for connecting a pnp transistor which can function as a switch or an amplifier. The above figure shows the structure and symbol of pnp transistor. So 3v is connected to the emitter of the transistor. Here if you observe the base current flows out of the base unlike npn transistor.
