The topic of this problem is Operational Amplifier Circuits.

And the problem is to determine V out and I out in the circuit shown below.

The circuit has an op amp, it has two voltage sources, a 12 volt and

a 2 volt source, and three resistors associated with it.

What we want to do is we want to use the properties of an ideal op amp

in order to help us solve this circuit.

So if we look at an ideal op amp, first of all, the symbol for

the ideal op amp has two inputs.

It has an inverting input and a non-inverting input.

And each one of those inputs have a current associated with it.

So we have a current for the non-inverting input and

a current for the inverting input.

We also have voltage associated with each one of these inputs as well,

for the inverting and non-inverting inputs.

If we want an ideal operational amplifier, we know that the current

going into the inverting input is equal to the current
