3. The current in a series circuit depends on which resistor you are looking at
T/F
5. An ammeter has little or no resistance
T/F
7. The force that a charge feels when near a magnetic field always points in the same direction that the charge is moving.
T/F
8. Reflection depends on the relative speed of light in different materials (known as the index)
T/F
