I'm currently enrolled in a lab class about circuits. we are doing diodes, transistors, op-amps these days.(adsbygoogle = window.adsbygoogle || []).push({});

the thing is, I've never taken any circuit analysis before, but the prof. expects us to be able to understand op-amp, diodes, transistors... and be able to calculate quantities for complicated circuits involving these things.

My question is what equation governs ideal transistor and op-amp?

for instance, for resistor, V=IR.

what about transistors and op-amps? I have searched for many books in the library (they are either too complicated or too simple to include diodes) and struggled with my book (the book is like a layman introduction to circuits... I don't like that style... the math is sketchy and derivations are usually omitted)

I know for ideal transistor, current through emitter = current through collector...is that correct? what about voltage?

and for op-amp... I really don't know.

so for op-amp, what is the governing equations/relations regarding

1. -input

2. +input

3. output

in terms of voltage and current?

I just need to know the fundamental equations about these things... It will be appreciated if anyone can help me... thx for your reading.
