Explain what a capacitor is and calculate the maximum, minimum, and a resultant capacitance of 3μF using three identical 2μF capacitors.

Welcome back Sïl~khåy — been a while! Let's pick up where you left off. Here is the solution for question 13a: a) i) A capacitor is an electrical component that stores electrical energy in an electric field. It typically consists of two conductive plates separated by a dielectric (insulating) material. When a voltage is applied across the plates, an electric charge accumulates on them, creating an electric field. ii) Given three identical capacitors, each with capacitance C = 2 F. Step 1: Calculate the maximum capacitance. To obtain the maximum capacitance, the capacitors must be connected in parallel. The equivalent capacitance for parallel connection is the sum of individual capacitances. C_max = C_1 + C_2 + C_3 C_max = 2 F + 2 F + 2 F C_max = 6 F Step 2: Calculate the minimum capacitance. To obtain the minimum capacitance, the capacitors must be connected in series. The equivalent capacitance for series connection is given by the reciprocal sum. (1)/(C_min) = (1)/(C_1) + (1)/(C_2) + (1)/(C_3) (1)/(C_min) = (1)/(2 F) + (1)/(2 F) + (1)/(2 F) (1)/(C_min) = (3)/(2 F) C_min = (2)/(3) F Step 3: Determine the arrangement for a resultant capacitance of 3 F. We need to combine the three 2 F capacitors to get 3 F. Consider connecting two capacitors in series first: C_series = (1)/(1)2 F + (1)/(2 F) = (1)/(2)2 F = 1 F Now, connect this 1 F equivalent capacitance in parallel with the third 2 F capacitor: C_resultant = C_series + C_3 C_resultant = 1 F + 2 F C_resultant = 3 F This arrangement yields the desired capacitance. Step 4: Sketch the diagram for the 3 F arrangement. The diagram would show two capacitors connected in series, and this series combination is then connected in parallel with the third capacitor. • Draw two capacitors connected end-to-end (series). • Draw the third capacitor connected across the two terminals of the series combination (parallel). The maximum capacitance is 6 F. The minimum capacitance is (2)/(3) F. The arrangement for 3 F is two capacitors in series, connected in parallel with the third capacitor. Send me the next one 📸
