Question

Find out the graph which shows the input, transfer and output characteristic curve of a transistor in common configuration?

• A. $A,C,B$
• B. $A,B,C$
• C. $C,A,B$
• D. None of these

Answer 1

The correct option is A $A,C,B$

In put characteristic of a transistor represents the variation of the base current $I_b$ with base emitter voltage $V_{BE}$ keeping $V_{CE}$ fixed.

Hence graph A shows the input characteristics.

Transfer characteristics is a graph plotted with base current $\left(I_b\right)$ along X-axis and output current $\left(I_c\right)$ along Y-axis by keeping output voltage $\left(V_c\right)$ constant.

Hence graph C shows the transfer characteristics.

Out put characteristics of a transistor represent the variation of collector current $I_c$ with collector emitter voltage $V_{CE}$ keeping $I_b$ fixed.

Hence graph B shows the output characteristics.
