  B) introduce a very small series resistance into the circuit whose current is to be measured.
  C) introduce a very large series resistance into the circuit whose current is to be measured.
  D) consist of a galvanometer in series with a large resistor.

Question 3

A mass spectrometer needs
 
  A) colinear magnetic and electric fields.
  B) perpendicular magnetic and electric fields.
  C) only a magnetic field.
  D) only an electric field.
  E) a perpendicular gravitational field.
