, What happens when power is applied in an Astable Multivibrator? - ANS Q1 and Q2 switch
between on or off.



What happens to Q1 and Q2 in a monostable multivibrator? - ANS Q2 is on, Input pulse
causes Q2 to turn off and Q1 to turn on



A transistor in a multivibrator is on in ____________ - ANS Saturation



A transistor in a multivibrator is off in __________ - ANS Cutoff



What happens to Q1 and Q2 in a bistable multivibrator? - ANS Either Q1 or Q2 could be on,
input pulse causes either to turn off and the other to turn on.



How is an Astable multivibrator identified? - ANS Two capacitors in the feedback circuit.



How is a monostable multivibrator identified? - ANS One capacitor and one resistor in the
feedback circuit.



How is a bistable multivibrator identified? - ANS Two capacitors and two resistors in
feedback circuit.



What is the purpose of R1 in an Astable Multivibrator Circuit? - ANS Collector Load Resistor



What is the purpose of R3 in an Astable Multivibrator Circuit? - ANS Base bias resistor for Q1
