If they both supply the same current in their circuits, which of the following statements is true?  a. External resistance in Source A’s circuit is more than Source B’s circuit.  b. External resistance in Source A’s circuit is less than Source B’s circuit.  c. External resistance in Source A’s circuit is the same as Source B’s circuit.  d. The relationship between external resistances in the two circuits can’t be determined.
