(b) A typical capacitor in a memory cell may have a capacitance of 7 x 10-14 F. If the voltage across the capacitor is 0.5V, determine the number of electrons that must move on the capacitor to charge it. [6 Marks] Given the circuit as shown in Figure 1. i) Redraw the circuit so that the series and parallel looks much easy to analyse. ii) Find the equivalent resistance, R, of the circuit. Given R₁-2.2k2, R=4.1k92, R=3.2k2, R4 10k2, R₁-2kQ2, R=4kQ2, R₁-8kQ2, R₁=1kQ, R=5.2kQ2, and R₁0=9.2kQ2. iii) Let it be supposed that Rs, R7, and Rs are shorted. Explain the effect to the total resistance compare with the original circuit. R₂ R₁₁ H R10 Figure 1 R7 R5 [13 Marks]
