Value of resistor for full scale deflection with 10A

  1. Feb 22, 2017 #1
    1. The problem statement, all variables and given/known data
    In order to provide full scale deflection the coil current required in a galvanometer is 190μA and the resistance of the coil in the galvanometer is 35Ω

    - What is the value of the resistor to be connected in parallel with the meter so that full scale deflection is obtained when the total current passing is 10A?

    - Determine the value of the resistor to be connected in series with the meter so that full scale deflection is obtained when the total voltage connected is 120V
    2. Relevant equations

    Not sure

    3. The attempt at a solution

    The galvanometer has it's own range for deflection. All I know about deflection is that it converts electrical energy to mechanical?

    Please draw sketches of the two problems, and show the equations that you would use to find the answers. Please show a bit more effort in this. Thanks.
