2) What is the voltage gain in a transistor if the input voltage in 40mv and the output voltage in 3.6V?

45 90 180 270

3) What is the input impedence of darlington pair transistors?

Very low input impedance Very high input impedance Medium input impedance Uniter

4) What is the advantage of using bias in transistor circuits?

Provides positive feed back Never reach saturation Easily sets saturated Gives maximum distortion
