Answer 3

how to calculate R for part b?

Answer 4

I=Vout/R1+R2 R1=R2

Answer 5

nurali...plzzzz help
Suppose that we need to put precisely i=9mA through a load that presents a resistance but the value of the resistance is not well controlled. Suppose also that we have a precision voltage source of v=5V, but this voltage source is pretty wimpy: it cannot supply more than 0.1mA without smoke coming out of it. With the circuit shown above we can choose a resistor of resistance R that can accomplish this goal.
First, assuming that the op amp is ideal (A=∞) give the value of the resistance R, in Ohms, that we need.

Answer 6

for part 1
R1=v/i

Answer 7

tell me value Vs.

Answer 8

i have the values Vs=17V

Answer 9

hey for part c..... answer will be from the R of part a
i=(Vi/R(1+((R+Rl)/R*A))

Answer 10

tell me the value of Rl so that i could find values for your question's part C
