A galvanometer has an internal resistance of 100 ? and deflects full-scale at 2.00 mA. What size resistor should be added to the galvanometer to convert it to a milliammeter capable of reading up to 4.00 mA, and how should this resistor be connected to the galvanometer?
Answer
a. 75.0 ? in parallel with the galvanometer
b. 50.0 ? in parallel with the galvanometer
c. 50.0 ? in series with the galvanometer
d. 100 ? in parallel with the galvanometer
e. 100 ? in series with the galvanometer
