Here are the essential concepts you must grasp in order to answer the question correctly.
Capacitance
Capacitance is the ability of a capacitor to store electrical energy in an electric field, measured in farads (F). It is defined as the ratio of the electric charge stored on one plate of the capacitor to the voltage across the plates. In AC circuits, capacitance affects how the capacitor reacts to changing voltages and currents, influencing the overall impedance of the circuit.

RMS Voltage
RMS (Root Mean Square) voltage is a statistical measure of the magnitude of a varying voltage. It represents the equivalent DC voltage that would deliver the same power to a load. In AC circuits, RMS voltage is crucial for calculating power and current, as it provides a consistent value for analysis, especially when dealing with sinusoidal waveforms.

Peak Current
Peak current refers to the maximum instantaneous current flowing through a circuit during one cycle of an AC waveform. It is important for understanding the behavior of components like capacitors in AC circuits, as it helps determine how much current the capacitor can handle at its maximum charge. The relationship between peak current, RMS voltage, and capacitance is essential for calculating the value of the capacitor.
