Q19.An n.p.n transistor with current gain β = 100 in common emitter configuration is shown in figure. The output voltage of the amplifier will be (1) 0. 1 V (2) 1. 0 V (3) 10 V (4) 100 V
What This Question Tests
This question requires analyzing a common emitter NPN transistor amplifier circuit to calculate the output voltage using the current gain (β) and Kirchhoff's voltage law for the output loop.
Concepts Tested
Formulas Used
I_C = β I_B
V_CE = V_CC - I_C R_C
V_out = V_CE
I_B = (V_in - V_BE) / R_B
