#Common Emitter Configuration
The Common Emitter (CE) configuration transistor is used in electronic circuits.
In this configuration, the emitter terminal is common to both the input and output sides.
The base-emitter junction is forward-biased while the base-collector junction is reverse-biased.
It provides amplification of current and voltage, making it suitable for amplifiers and switching applications.
The input signal is applied to the base terminal and the output is taken from the collector terminal.
The CE configuration offers high voltage gain but low current gain.
It requires a biasing circuit to ensure proper operation and stability.
The CE amplifier is widely used in audio amplifiers, signal processing, and digital logic circuits.
VIVA QUESTIONS:
Q: What is a transistor?
A: A transistor is a semiconductor device used for amplification and switching electronic signals.
Q: Mention the types of transistors.
A: Bipolar Junction Transistor (BJT) and Field-Effect Transistor (FET).
Q: Explain the operation of a BJT.
A: A BJT operates by controlling the current flow between its two terminals (collector and emitter) using a small current at the third terminal (base).
Q: Differentiate between NPN and PNP transistors.
A: NPN transistors have a positive voltage at the base relative to the emitter, while PNP transistors have a negative voltage at the base relative to the emitter.
Q: What is the common emitter(CE) configuration? A: The common emitter configuration is a transistor setup where the emitter terminal is common between input and output.
Q: Define cutoff, saturation, and active regions in a transistor.
A: Cutoff: No collector current flows. Saturation: Maximum collector current flows. Active: Transistor operates between cutoff and saturation regions.
Q: What is the purpose of the heat sink in a transistor?
A: A heat sink dissipates excess heat generated by the transistor to prevent overheating.
Q: How is a transistor biased?
A: Biasing a transistor involves applying a suitable DC voltage to the base-emitter junction to keep it in the active region.
Q: State some applications of transistors.
A: Transistors are used in amplifiers, oscillators, switches, digital logic circuits, and various electronic devices.

Thank you, Sir, This is very clear.

THANK YOU

[@aravindhsura3165]

Sir one doubt why dont u shorted. Vbe voltage in output characteristic

[@kreducationalduniya]

When you take out any voltmeter (Vbe) you should not short. The equipment will get damage.
