8. What is Resistance

  • A measure of the rate of energy transfer.
  • A measurement of the flowcharge in a circuit.
  • A measure of how difficult it is for current to pass through a wire.
  • A measure of the current passing through a wire.

9. What is the value of a giga-amp (GA)

  • 1*10^9 A

10. How is resistance caused

  • A change in length in the wire
  • Caused by the kinetic energy of the particles decreasing
  • Caused by the collisions of the charge carriers with each other
  • Caused by the current through the wire being halved.
