The voltmeter reads 0.22 V. is positive, so point a is at higher potential. Reflect: Since there is no current in the middle branch, the two resistances in that branch could be removed without affecting the potential difference The 10.0 V emf doesn’t affect the current but does affect 19.90. Set Up: The charge is reduced to of its maximum value when Solve: (a) At (b) 19.91. Set Up: At Solve: (a) At and (b) so 19.92. Set Up: Zero current through the galvanometer means the current through N is also the current through M and the current through P is the same as the current through X . And it means that points b and c are at the same potential, so Solve: (a) The voltage between points

    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.
