Problem $6\mathrm{.}8$

Find the Thevenin equivalent seen between the non$-$inverting terminal node and the reference node in Figure P$6\mathrm{.}8.$

Solution:

Known quantities:

The circuit of Figure P$6\mathrm{.}8$

Find:

The Thevenin equivalent connected to the two terminals of the op$-$amp.

Analysis:

First simplify the circuit to a simple loop including the two voltage sources, $R_1,$ and $R_2.$
