Hello Friends,
I always land up in confusion or doubt when i try to use an Opamp. Theoretically i have read about it's charecteristics, modes of operation and compenastion techniques involved with it. But, when it comes to driving a transistor or some other device through an Opamp, iam getting strucked up. i could not get a clear picture of the current directions at the output of Opamp for a particular type of input and hence could not analyse the possible ways by which a load or any other device could be connected to it thus making the effective use of input. So i thought of putting it here to get some knowledge of it.
It would be fine if i could get some help with this.

How should i approach to get familiar in driving different type of loads. So that i could do on my own.

Is there any material that describes the funtionally of Opamp with practical examples.

When i searched net, i couldnt get anything of satisfaction.

regard's
Suresh.
