[19] 1 A circuit consists of two bulbs (A and B) with different resistances connected in series. Bulb A has smaller resistance in compared to bulb A. When the switch is ON, all bulbs shine (emit light). Use your knowledge of electric fields to answer the following questions: 4.1.1 Explain what causes the bulbs to shine. (3) Page 8 of 15 4.1.2 Which bulb shines brighter? Explain (2) -.2 Five resistors are connected as shown in the diagram. The potential difference between points A and B is 15 V. Calculate 4.102 A 3.20 32.792 2.402 min 3.622 4.2.1 the equivalent resistance between the points A and B. (4) B
