A battery with an emf of 12 V theoretically supplies 4 A of current to the circuit's load if internal resistance is not taken into consideration. When the internal resistance is included, the current is calculated to be 3 A. The load's resistance, R, and the internal resistance, r, are
  1. R = 1 , r = 3
  2. R = 1/3 , r = 11/3
  3. R = 3 , r = 1
  4. R = 3 , r = 4

Question 2

A circuit element uses 50 watts of power. The current running through it is 5 A. Which of the following could be the circuit's resistance and potential difference?
  1. 10 V, 2
  2. 20 V, 8
  3. 20 V, 4
  4. 15 V, 4.5
