## Homework Statement

Calculate Vout if

a) I=1mA, R1=2.2kΩ, and R2=1kΩ;

b) I=2A, R1=1.1Ω, and R2=8.5Ω.

c) For each case, state whether the circuit is wired as a non-inverting or an inverting amplifier.

NOTE: I is set to 1mA in the circuit below.

## Homework Equations

Req=(R1*R2)/(R1+R2)

V=IR

## The Attempt at a Solution

First, I calculated Req for R1 and R3:

Req=(2.2kΩ*1kΩ)/(2.2kΩ+1kΩ)=687.5Ω

I then converted the current source to a voltage source:

V=(1mA)(687.5Ω)=687.5mV

Am I going in the right direction? This seemed like an easy problem, but I don't know if I'm doing it right.
