Q1: The modulation of effective base width by collector voltage is known as Early effect, hence reverse collector voltageA
increases both a and β
B decrease both a and β
C increase a but decrease β
D decrease a but increase β
ANS:C - increase a but decrease β Because of reach through effect, the effective base width becomes zero and hence, base current Ib reduce. So beta will increase and also alpha will increase beta = Ic/Ib and alpha = Ic/Ie. |
