Question

Consider the circuit shown in the below Figure and its load line characteristic. The x-intercept of the load line is 

• A. 3.6V
• B. 0
• C. 1.8V
• D. 1V

Hint:

The x-intercept of the load line represents the maximum collector-emitter voltage. Remember the supply voltage contributes to the maximum value.

Answer 1

The Correct Option is A

The x-intercept of a load line in a transistor circuit is the point where the load line crosses the \(V_{CE}\) axis (horizontal axis), which gives the value of the voltage when the transistor is cut off. This occurs when \(I_c\) = 0. Here, the total voltage supply is \(1.8V - (-1.8V) = 3.6V\), thus the x-intercept of the load line is 3.6V.
