(Originais Teachy 2023) - Question Medium of Physics

In a Physics experiment, a 2nd-year high school student needs to calculate the equivalent capacitance of a circuit containing three capacitors in series. The individual capacitors have capacitances of 2 µF, 4 µF, and 6 µF, respectively. The student remembers the rule that states the equivalent capacitance of capacitors in series is the inverse of the sum of the inverses of the capacitances, but he gets confused when applying the formula. Since the series of capacitors is inserted in a circuit that also includes a constant voltage source of 12 V, the student is asked how the capacitance of the circuit affects the charge storage capacity. The question is: 1) Calculate the equivalent capacitance of the circuit for the three capacitors in series and explain in detail the reasoning used. 2) Discuss how the equivalent capacitance affects the charge storage capacity of the circuit and relate this effect to the theory of capacitors.
