Unformatted text preview: P 5.4 Since the current into the inverting input terminal of an ideal op—amp is zero, 0, therefore '00 = 9'01, - 8va the voltage across the 3.3 M9 resistor is (3.3 X 106)(2.5 X 104) or 8.25 V. Therefore the voltmeter reads 8.25 V.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
