, Ans > One stable state, it is triggered

8. A bistable multivibrator has..

Ans > Two stable states, it is triggered

9. A stable state is...

Ans > A steady condition(output stays the same)

10. What happens when power is applied in an Astable Multivibrator?

Ans > Q1 and Q2

switch between on or off.

11. 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

12. A transistor in a multivibrator is on in

Ans > Saturation

13. A transistor in a multivibrator is off in

Ans > Cut off

14. 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.

15. How is an Astable multivibrator identified?
