A battery placed in circuits with different load resistances can be considered as a source of constant
  1.emf.
  2.current.
  3.terminal voltage.
  4.nothing.

Question 2

In order to calculate the fraction of the total power delivered to the load resistor in a circuit consisting of a battery and a load resistor, one needs to know only the
  1.load resistance.
  2.internal resistance.
  3.load resistance and internal resistance.
  4.emf, load resistance, and internal resistance.
