Transistor — Load LineMediumQuestion 20241
Question
The DC load line in a transistor circuit connects:
- AV_CC/R_C on the I_C axis to V_CC on the V_CE axisCorrect
- BOrigin to maximum power point
- CSaturation point to cutoff point
- DBase current values
Correct answer
V_CC/R_C on the I_C axis to V_CC on the V_CE axis
Explanation
From V_CC = I_C × R_C + V_CE: when I_C = 0, V_CE = V_CC (cutoff); when V_CE = 0, I_C = V_CC/R_C (saturation). The load line connects these two points on the I_C–V_CE characteristic. The Q-point (operating point) is where the load line intersects the base current curve.
