Question

From the figure , write note voltage equations, one for each input terminal of the op amp
The expression for the load current ( i_L) can be written as a function of the input voltage (V_in) and the load voltage (V_L)

I_L₌A(V_in) + B(V_L)

b.1 What is the expression for A?

b.2 What should be the condition for R₁ R₂ R₃ R₄so that B is zero? (NB this will make( i_L) depend only on V_in and not on R_L)
