Quiz 2 -- dc Circuits

simple circuit

Two lightbulbs are connected in series with the battery shown.

  1. What is the voltage difference between a and b? (That is, what is the terminal voltage of the battery?)

  2. A third identical lightbulb is now connected in parallel to one of the other lightbulbs. By what percentage does the power dissipated by the internal resistance change?
