Questions for Experiment $24$

The calculated base voltage in Table $24-1$ is approximately:

$($a$)10\mathrm{.}8$ mV ;

$($b$)20$ mV ;

$($c$)250$ mV ;

$($d$)500$ mV $.$

The calculated collector voltage in Table $24-1$ was closest to:

$($a$)10\mathrm{.}8$ mV ;

$($b$)20$ mV ;

$($c$)250$ mV ;

$($d$)500$ mV $.$

In Table $24-2,$ the measured base voltage was closest to:

$($a$)12$ mV ;

$($b$)20$ mV ;

$($c$)63$ mV ;

$($d$)1$ V $.$

The voltage gain from base to collector in the swamped amplifier was closest to:

$($a$)1$ ;

$($b$)5$ ;

$($c$)10$ ;

$($d$)15.$

Compared with the CE amplifier, the swamped amplifier had a :

$($a$)$ lower input impedance;

$($b$)$ higher output impedance;

$($c$)$ lower voltage gain;

$($d$)$ lower ac collector voltage.

Explain why an amplifier with a swamping resistor has a more stable voltage gain than one without.
