Question

Question 1
The elements in the circuit have the following values: R=5kΩ and rm=15kΩ
Assuming that iN1=1mA and iN2=0A, what is the value of vOUT in Volts?

Assuming that iN1=0A and iN2=1mA, what is the value of vOUT in Volts?

Assuming that iN1=1mA and iN2=1mA, what is the value of vOUT in Volts?
Assuming that Input 2 is left as an open circuit, what is the Thevenin equivalent resistance (in kOhms) seen from Input 1?

Answer 1

try the formula,, for part 1 : iA = 2*i1*R/(2*R+rm)
for part 2 : iA = i2*R/(2*R+rm)
Part 3 is : iA(part 1)+iA(part 2)

Answer 2

part 4 is R+R OR R+rm

Answer 3

and what wer the answers u got

Answer 4

R=3kΩ and rm=12kΩ
the formulas obtained
0.00033
0.000166
0.000496
6k
all wrong

tell me what I'm doing wrong?
