What is hysteresis and how do I control it?

[NukeEngineer]

Hello,

I'm having some problem in understanding what is hysteresis. can someone explain it to me what is hysteresis, and how can i make the value big or small as i wish?

 

[PhysicoRaj]

Are you asking generally about hysteresis? Or do you refer to any of it's specific types?

 

[NukeEngineer]

hysteresis in general. how about it?

 

[PhysicoRaj]

Have you tried the wiki? It gives a nice explanation.

 

[NukeEngineer]

oh yeah I've tried. it's great. thanks. btw do you happen to know how can i change the value as i wish in circuit? like increase the resistor value or something like that?

 

[PhysicoRaj]

If you want to increase the resistor value, use a resistor of higher value.

Please take the time to think your question through and state it clearly.

What circuit ?

It's disrespectful to ask somebody to invest effort when you won't.
That's why you are getting dismissive answers.

Attitude is everything.

ah, I've got the solution. it's op-amp based circuit by the way. thank you, and sorry for the lack of information in my question.

I like that. Indeed, an astute description, Jim.
