Oscillator With AC Power

03/18/2015 10:33 AM

What happens if we give ac power to power up the oscillator circuit instead of dc power??

Either it will oscillate, or it won't, or it will produce smoke. Have you all tried it yet?

You de-modulate the baseline noise generator that initiates all oscillators allowing you to decode the dark matter between the valance electrons and the nucleus thus providing the envelope signal necessary for the input driver of the flux capacitor.

If there are logic chips involved they will probably be destroyed.

If there are transistors involved they will probably be destroyed.

If there is a bridge rectifier involved you may get away with it if the voltage is suitable.

The question is ill defined and rather silly.

What will happen if I fill my car engine with marmalade instead of oil?

No matter what, the term "Oil fill" does NOT mean fill it up all the way.....what a mess, oil all over the driveway......Shazizzle!

Ohh, it could be done, nothing is impossible in the advent of James Stewart these days. A matter of frequency modulation and kaboom- where is the kaboom, wait, there should be a kaboom.

You probably will get nothing but smoke. (Particularly if this is power grid AC voltage.) You might get just a constant oscillation. You might an amplitude or frequency modulated oscillation. It all depends on the oscillator circuit and the amplitude, frequency and placement of the AC power applied.

Orange or ginger marmalade? I'm very fond of the ginger marmalade.

Ginger and rhubarb for me, please. And some hot buttered toast. There has to be toast. Hey - we could use a smoking oscillator to make it!

I have see this when sweeping floor nearby of smart guys working on machine and my thinking drift off into sleepy eyes hearing voice say"What happens if we give ac power to power up the oscillator circuit instead of dc power??" I waked suddenly hand slip from broom with face hitting floor.

Perhaps the face needs DC power instead of AC. Is your broom imperial or metric?

It depends on the circuit of course (as I believe we have mentioned before there are mannnnnnny different types and configurations). If it isn't designed to run on AC it will probably be either destroyed or just not work.

I would suggest you study up on oscillators more so you have a better understanding of the fundamentals and basics. Plenty of free resources available on the internet.

Probably about the same thing as when you plug a 110VAC appliance into a 220VAC outlet!

The oscillator works because of the magic smoke inside. Applying AC will release the magic smoke, and the oscillator will no longer oscillate.

Hey you educated or uneducated electronic fools why you are make the discussion side track?? If you dont know the answer then comment your worthless comments in facebook. Did i mentioned that i am giving 110 or 220 vac. I am giving a 12vAC from a step down transformer. Now answer if you have the real stuff not like lyn.

You know you didn't.

Now answer if you have the real stuff not like lyn.

No, that's it I have also had it with you, and as other people on CR4 will attest to that takes some work for me to get mad.

Your attitude is appalling, you don't perform simple research yourself, your in violation of numerous CR4 rules, you don't listen to those of us that post answers (and even argue), you don't answer follow up questions we ask when we try and help and you expect (no demand) us to provide you all the answers while apparently doing no work yourself and many of your questions appear to be homework.

In addition you keep asking questions supplying us so little information we couldn't answer even if we wanted to. Hench most people have given up and are posting off topic answers. For example, asking for a FM transmitter circuit but refusing to give ANY further information when asked, even a second year student should realise this is ridiculous!

That's not how an online forum works, that is not how Engineering works in the real world. Oh, and posting threatening messages anonymously to CR4 users has NOT gone unnoticed. Yes we know what you have been doing, and doing this in the real world will get you fired from a job.

Grow up, get off you high horse and get in the real world. Start doing your own research and then ask proper questions providing proper details and answering follow up questions and we may answer you. There are thousands and thousands of other year two students in India in your position, if you expect to get given a job dream on, you have to work for it!

Put in the damn effort yourself with the fundamentals and perhaps we will help you in the future with elements of the more technical questions if you ask nicely and follow the CR4 rules.

Although others haven't bothered to put the time in to post the gist of the above comments I believe many if not most agree with me.

And to step up shoulder to shoulder, yes, I HAVE NOTIFIED CR4 Admins personally, several times, to check this nitwit out.

Shoot, I've worked throughout my career with a LOT of engineers from India (and have several young ones among my good friends now, even though I'm retired). If I showed them this nut's posts, it would embarrass them.

It will oscillate with increasing amplitude during the positive half cycles and stop oscillating during the negative half cycles.
The durability of the transistors will depend on the current during the negative half cycles via the resistors in the circuit.
In most cases it will be very reliable and a very good design.
It will win first place in the ingenuity section of the science awards section.
