ELECTRONIC PRACTICE - Quiz

1) What is the power gain of CE amplifier with a voltage gain of 66 and Beta of the transistor is 100?

1.5 166 0.66 6600

2) What is the effect, if SCR is latched into conduction and gate current is removed in DC?

SCR gets cut off Current through SCR OFF Output voltage will be reduced Gate looses control over conduction

3) What is the effect of pinch-off voltage in JFET?

No depletion region exists Drain current becomes zero Reverse bias voltage becomes zero Width of channel has maximum value
