The battery powering a light bulb is disconnected. As the light bulb's heat dissipates, how will the resistance and current change?
  1.The resistance will decrease and the current will increase.
  2.The resistance will increase and the current will be zero.
  3.The resistance will increase and the current will decrease.
  4.The resistance will decrease and the current will be zero.

Question 2

Which of the following best describes the inner workings of conductors?
  1.Electrons collide at random, experiencing a net change of position equal to zero, except when exposed to an external electric field.
  2.The electrons start at one electrode and travel directly to the other electrode, stopping there.
  3.The electrons' drift speed depends only on the material of the conductor and not on the voltage difference applied to it.
  4.None of these choices is correct.
