Charge Storage Mechanism The primary function of a capacitor is to store electric charge. When a voltage is applied across the conductive plates, an electric field is created, causing positive charge to accumulate on one plate and negative charge on the other. The dielectric material plays a crucial role in this process by preventing the charges from flowing directly between the plates, thus maintaining the separation of charge. B. Capacitance and Its Significance Capacitance is defined as the ability of a capacitor to store charge per unit voltage. It is measured in Farads (F), with one Farad being the capacitance when one coulomb of charge is stored at one volt. The capacitance of a capacitor depends on several factors, including the surface area of the plates, the distance between them, and the properties of the dielectric material. C. Mathematical Representation The relationship between charge (Q), voltage (V), and capacitance (C) is expressed mathematically as: \[ C = \frac{Q}{V} \] Where: - \( C \) is the capacitance in Farads, - \( Q \) is the charge in coulombs, - \( V \) is the voltage in volts. This formula highlights the direct relationship between the amount of charge stored and the voltage applied across the capacitor. V. Capacitor Charging and Discharging A. Charging Process When a capacitor is connected to a voltage source, it begins to charge. The current flows into the capacitor, causing the plates to accumulate charge. The time it takes for the capacitor to charge to approximately 63% of the applied voltage is known as the time constant (τ), which is determined by the resistance (R) in the circuit and the capacitance (C) of the capacitor: \[ \tau = R \times C \] The time constant is crucial in determining how quickly a capacitor can charge or discharge. B. Discharging Process When the voltage source is removed, the capacitor begins to discharge, releasing the stored energy back into the circuit. The voltage and current during the discharging process decrease exponentially over time, following the equation: \[ V(t) = V_0 e^{-\frac{t}{\tau}} \] Where: - \( V(t) \) is the voltage at time \( t \), - \( V_0 \) is the initial voltage, - \( e \) is the base of the natural logarithm, - \( \tau \) is the time constant. This exponential decay is a fundamental characteristic of capacitors, influencing their behavior in various applications. VI.
