    Hello guys...How are you?

    In this op amp circuit, I need to find the max and min V(input) such that V(output) is within (-13,+13), which is question (c). And also, I need to find an answer to question (d) which is about the min load resistance (RL)...


    NOTE: In question (d) the load resistance is (RL) not as it says (R2).

    Good Buy :)

    Would you mind attaching your file using the sites attachment feature rather than subject the members to the advertisements and popups of the image sharing service?

    Here is the circuit again ;)

    In fact, I have solve it but I got an unreasonable input Voltage (140 V)!!!

    I think there is something wrong with the values of the resistors ?)

    TELL ME IF YOU GOT THE SAME ANSWER

    Good buy...

    Can you show the calculations that gave the 140 volt input voltage?
