8. A galvanometer has a coil resistance of 100 ohms and gives a full scale deflection when the potential difference across it is 0.0002 V. What size resistor (with a value measured in ohms) is required to make a 1.0 A. full scale deflection ammeter?

    current for meter: .0002/100=2E-5 amps

    so the shunt should carry .(1-2E-5) amps
    and the resistance =.0002/(1-2E-5) ohms

    2E-3/(.99999) ohms
