page 16 21. A student carries out an experiment to determine the EMF and internal resistance of a battery using the circuit shown. V A The resistance of the variable resistor is altered and readings of voltage V and current I are taken. These readings are used to produce the following graph. V (V) I (A) 0.0 0.5 1.0 1.5 2.0 2.5 3.0 6.0 5.0 4.0 3.0 2.0 1.0 0.0 Which row in the table shows the EMF and internal resistance of the battery? EMF (V) Internal resistance (Ω) A 2.0 6.0 B 5.0 0.50 C 5.0 2.0 D 6.0 0.50 E 6.0 2.0
