A
25
alpha-beta relation
26
which is almost 1 in magnitude and which is in large magnitude?!

27
draw the common-emitter circuit diagram with labeling
28
output voltage formula
29
input voltage formula
30
output resistance formula
31
whats zero at saturation current
32
input resitanfce formula
33
input characteristic curve graph
34
output characteristic curve graph
35
which property of common emitter circuits is used in amplifiers
a slight change in the input can result in a massive change in output which property is used in amplifiers in common emitter circuits
36
by how much phase does the common emitter amplifier change the output voltage
180
37
voltage gain formula
38
power gain formula
39
why does zener breakdown occurs
it occurs due to the breaking of covalent bonds in the depletion layer and increase in the number of electrons resulting in the sudden increase in the current in the circuit
40
in which biasing does zener breakdown occurs?
in reverse biased
41
what is the graph of zener breakdown
42
what happens if in a zener diode circuit the current across resistance of zener is much more than the total curretn
the diode isnt in zener breakdown and hence the current though zener diode is 0
