## Homework Statement

## Homework Equations

Is 1 an ideal voltage source?

Is 2 and ideal current source?

i was solving a noninverting amplifier circuit and i was asked to find out output impedence.

and in the first circuit output voltage was independent of the load resistence => output impedence=0 så it should be the first fiqure i have drawn. because output acts as a perfect voltagesource.

I the other question

i found out that current throug the load resistece was independent of the load res.

then out impedence should be infinity.

Does out put acts as a idela current source ?
