it is about thefiltering of the ac signal from the circuit. when transistor2 switched on, collector terminal is suddenly shorted to ground and voltage at collector2 drops to vce from vcc.it cause a negative voltage pulse. the negative pulse coming at the collector of 2nd transistor passes to base of 1st transistor and thus transistor1 is switched off. commutating capacitors will allow to pass the ac signal only. so the negative pulse at the 2nd collector alone is feed to the base of 1st transistor. that is function of commutating capacitor

Why use of Multivibrator?
it gives a nice pleasurable experience
How monostable multivibrator can be used to generate?
we can use monostable multivibrator.But generally its o/p is a square wave so to get a pulse type waveform,we may use differentiator after monostable multivibrator....
How can you use a 3 phase capacitor as a single phase capacitor?
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
How do you determine if the capacitor is defective?
To determine if a capacitor is defective, use an Ohmmeter of a Multimeter.
Why you use capacitors in power supply?
You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.
Difference between monostable multivibrator and astable multivibrator?
No, cant use bistable multivibrator in place of monostable multivibrator... because monostable is meant for one stable state and one unstable state.. so there will be a constant time period for the alternate pulses of output.. but in bistable multivibrator, both are stable states.. so there is no specific time period for the output pulses.. the state will vary only on the application of mannual trigger...

Why do you use npn transistors in an astable multivibrator?
You can create an astable multivibrator with PNP, NPN, FETs, or even with NOR gates, NAND gates, or NOT gates. In fact the escapement movement in a mechanical watch is a species of astable multivibrator.

What is the use of rvt in capacitor bank?
Use of rvt in capacitor bank
Can you use a 25K capacitor instead of a 2.2K capacitor?
In general, no. You need to use the correct capacitor as designed for the circuit.
Can you use a run capacitor in place of a start capacitor?
No
What is the use of resistance in timer?
The resistor and capacitor helps you to adjust the time period (or frequency) of the timer. (Usually astable multivibrator is used as a timer in electronic circuits) More the resistance, less is the current flowing through it. If the current flowing through is it to charge the capacitor is less, then the capacitor charges slowly. The timer changes it's state when the capacitor charges to a specific voltage ( Usually 1/3Vcc or 2/3Vcc). As it is made to charge slowly due to the high resistance, the clock frequency decreases. In the same way, to increase the frequency of the timer, the resistance value needs to be reduced.
What products use the capacitor?
The products that uses the capacitor are filters and oscillators.
How one can know that what kind of capacitor to use in circuit?
paper capacitor
