Can u solve this op amp ?

[Zeeshan Sajid]

I have inserted a file. Please specify type of op amp and provide solution. I need complete solution and of course you have to do it for free. Your time and work will be really appreciated.. Thank you so much if u can help me solve this

 

[Zeeshan Sajid]

Kindly provide accurate formula for calculating V out in this circuit.. No guess please..

so how about you showing what you have learnt so far about Op-amps ?

we are not going to just supply direct answers, you need to make an effort

I have tried alot of options and formulas but i dont know what is correct one?? Friend of mine told me its voltage follower...but i have not seen op amp like this before.. I am not expert in op amp so if u knw exactly what type this is .. It will help me alot

why don't you start from the basics of assuming that Vout = a * (V+ - V-) and work from there.

Sir can u just tell me what type it is??

we will help you with your homework but we won't do it for you.

Ok.. Thanx any ways for all HELP

No problems. Thanks for your DEMANDS.

as Steve said, work backwards.

Assume the output voltage is Vo.
Workout the voltages at the + and - terminals, and the currents flowing in the resistors.

The problem states it is an ideal op-amp. You won't find one of those anywhere, so using a simulator is not going to solve your problem unless you create a sim model with ideal op-amp characteristics. An ideal op-amp has zero bias current, zero differential offset voltage between the inverting and non-inverting inputs, infinite open-loop gain, infinite bandwidth, zero output impedance, and infinite output voltage swing with infinite slew rate at any load current. It is also unconditionally stable with any closed-loop negative feedback network applied to it.

Most of us here get by with commercially available op-amps that are bit more fussy and far from ideal. Sorry about your luck and current lack of circuit analysis skills.

Also really sorry about @Zeeshan Sajid's attitude. Perhaps we have a language/cultural problem and not an electronic problem?

If I were a moderator, I would have closed this thread after post #8.

If I were a moderator, I would have closed this thread after post #8.

I was just waiting to see if he would come back with some answers to questions on what he has discovered /learnt so far
but responses have been lacking .... was giving the OP a fair and reasonable chance

so yes
Thread now closed
