It is defined as the ratio of the electric charge (Q) stored on one plate to the voltage (V) across the plates. The formula for capacitance (C) is given by: \[ C = \frac{Q}{V} \] 2. Formula and Units (Farads) The unit of capacitance is the farad (F), which is defined as one coulomb per volt. However, farads are often too large for practical applications, so capacitors are commonly rated in microfarads (µF), nanofarads (nF), or picofarads (pF). B. Types of Capacitors Capacitors come in various types, each suited for specific applications: 1. Ceramic Capacitors These are made from ceramic materials and are widely used for their stability and reliability. They are often found in high-frequency applications. 2. Electrolytic Capacitors Electrolytic capacitors are polarized and typically used for larger capacitance values. They are commonly found in power supply circuits. 3. Film Capacitors These capacitors use a thin plastic film as the dielectric. They are known for their low loss and stability, making them suitable for audio and high-frequency applications. 4. Tantalum Capacitors Tantalum capacitors are also polarized and offer high capacitance in a small package. They are often used in compact electronic devices. 5.

Charging and Discharging Process When a voltage is applied to a capacitor, it begins to charge, accumulating electrical energy. The charging process continues until the voltage across the capacitor equals the applied voltage. When the capacitor discharges, it releases the stored energy back into the circuit. B. Energy Storage and Release Capacitors store energy in the electric field created between their plates. The energy (E) stored in a capacitor can be calculated using the formula: \[ E = \frac{1}{2} C V^2 \] This equation shows that the energy stored is proportional to both the capacitance and the square of the voltage. C. Role in AC and DC Circuits In DC circuits, capacitors charge to the supply voltage and then maintain that voltage until they discharge. In AC circuits, capacitors continuously charge and discharge, allowing them to pass alternating current while blocking direct current. D. Impedance and Reactance Capacitors exhibit impedance, which is the opposition to alternating current. The reactance (Xc) of a capacitor is given by the formula: \[ X_c = \frac{1}{2 \pi f C} \] where \( f \) is the frequency of the AC signal. This means that the reactance decreases with increasing frequency, allowing capacitors to pass higher frequency signals more easily. IV. Applications of Capacitors A.
