Question 5 (Total of 10 marks) 0.40 uF 0.40 uF C1 C2 12 V H 0.20 uF 0.60 uF C4 Figure 5.1 a. Figure 5.1 depicts a circuit in which FOUR (4) capacitors, namely C1, C2, C3 and C4 are arranged in a parallel-series combination. Based on this diagram, determine the following: i. The equivalent capacitance for the entire circuit in Figure 5.1. (1 mark) ii. The voltage across each of the 4 capacitors (i.e., voltage across C1, C2, C3 and C4). (4 x 1/2 mark) iii. The charge on each of the 4 capacitors (i.e., charge on C1, C2, C3 and C4). (4 x 1/2 mark) b. Suppose you have FOUR (4) 12 uF capacitors. Draw diagrams to show how you could arrange all four capacitors in a series-parallel combination circuit so that the equivalent capacitance is i. 4.8 uF (2 x 2 mark) ii. 9.0 uF (2 x 12 mark) iii. 7.2 uF (2 x 12 mark) c. Two parallel-plate capacitors are made from circular plates. The first capacitor has circular plates with the radii rı = 12.3 cm and a spacing between the plates of 2.34 mm. The second capacitor has circular plates with the radii r2 = 14.8 cm. If the two capacitors have the same capacitance, what is the spacing between the plates in the second capacitor? (80 = 8.85 x 10-12 F/m). (2 x 1 mark)
