Question 2

When a 100- resistor is connected across the terminals of a battery of emf  and internal resistance r, the battery delivers 0.794 W of power to the 100- resistor.
 
  When the 100- resistor is replaced by a 200- resistor, the battery delivers 0.401 W of power to the 200- resistor. What are the emf and internal resistance of the battery? A)  = 10.0 V, r = 5.02
  B)  = 4.50 V, r = 4.00
  C)  = 9.00 V, r = 2.04
  D)  = 9.00 V, r = 1.01
