a. Two capacitors, one 7.5 µF and the other 15 µF, are connected in series across a 12.0 V battery. Determine the equivalent capacitance of these two capacitors and find the charge stored on each of these two capacitors. (4 × % mark) Figure 5.1 12.0 V Figure 5.2 2.56 μF [7.22 µF 4.25 µF b. The circuit in Figure 5.1 depicts five capacitors arranged in both series and parallel configurations. Based on this information, determine the following: (i) The equivalent capacitance of this circuit. (ii) The charge that flows from the 12.0 V battery. (iii) The voltage across the 2.56 µF capacitor. (iv) The charge stored in the 4.25 µF capacitor. (v) The charge stored in the 8.35 µF capacitor. (vi) The voltage across the 8.35 μF capacitor. Represents an electron 12 μF 8.35 μF (2 x ½ mark) (2x% mark) (2 x ½ mark) (2 x ½ mark) (2 x ½ mark) (2 x ½ mark) c. Figure 5.2 depicts the interaction between the atom (unknown element "X") which is added to the atoms of an intrinsic semiconductor (silicon, Si). Based on this diagram, deduce if the molecular structure depicted in Figure 5.2 belongs to a N-type semiconductor or a P-type semiconductor. Provide TWO observations to justify your answer.
