Multirange Voltmeter

  1. Oct 5, 2009 #1
    Can someone please help me out with this problem? I am not sure if what I am doing

    question:
    The figure below shows the internal wiring of a "three-scale" voltmeter whose binding posts are marked , 3.00 V, 15.0 V, and 150 V. When the meter is connected to the circuit being measured, one connection is made to the post marked + and the other to the post marked with the desired voltage range. The resistance of the moving coil is Rg, and a current of I in the coil causes it to deflect full scale.

    we know v=i/r and Vcoil=IgRcoil

    dont know where to begin

    sorry forgot to mention that. you have to find R1, R2, R3. Also find the overall resistance of the meter on a 3.00, 15.0, 150 V-range

    Why don't you state the entire text of the problem, verbatum? It should have a question mark somewhere to be answered.

    What is R1, R2, R3 and what is the overall resistance of the meter on a 3.00, 15.0, 150 V-range? that what its asking
