Question 78: Semiconductors and Logic Gates

Question

An n.p.n transistor with current gain $$\beta=100$$ in common emitter configuration is shown in figure. The output voltage of the amplifier will be

Accepted Answer

$${{{V_0}} \over {{V_i}}} = \beta  	imes \left( {{{{R_C}} \over {{R_B}}}} ight)$$
$$ \Rightarrow {V_0} = 100 	imes \left( {{{10} \over 1}} ight) 	imes {10^{ - 3}}$$
$$ = 1.0$$ V

Answer

0.1 V

Answer

1.0 V

Answer

10 V

Answer

100 V
