4:59 PM Thu 28 Apr Question z то A voltage applied to a circuit is called an Electromotive Force, E (emf) a) What is an electromotive force? (3 marks) b) A battery of 12 V and internal resistance (r) is connected in a circuit with three resistors each having a resistance of 102 as shown below. A current of 0.50 A flows through the battery. 10 2 12 V 10 22 102 (i) What is the potential difference between points A and B in the circuit? (4 marks) (ii) What is the internal resistance (r) of the battery? (3 marks) (iii) What is the total energy supplied by the battery per second? (2 marks) (iv) What percentage of power provided by the battery is delivered across the individual 10 resistor? (3 marks) 23% 1 > s
