🔋 Capacitors are devices used to store electric charges.

📏 Capacitance depends on the dimensions of the capacitor, such as area and distance between plates.

💡 When a capacitor is connected to a battery, electrons move from the positive terminal to one plate, storing charge.

⚡️ The capacitor stores electrical charge based on the voltage and capacitance values.

🔋 Different types of capacitors have specific applications, such as electrolytic capacitors in power supplies.

⚠️ Polarized capacitors should be connected correctly to avoid damage.

Capacitor values can be represented in different units such as microfarads and picofarads.

Capacitor values can also be represented using a color code system.

The maximum voltage specification is important when purchasing a capacitor.

⚡️ Capacitance can be varied by adjusting the distance between the plates.

🔧 A device called a variable capacitor is commonly used to adjust capacitance.

🔌 In a circuit with a capacitor, resistance slows down the flow of electrons and increases charging time.

🔑 When the switch is closed, the voltage across the capacitor increases to the source voltage, while the voltage across the resistor decreases to zero.

📝 There is no movement of charge or current through the capacitor, as the current flows externally through the circuit.

⏰ The time it takes for the capacitor to charge fully depends on the RC time constant, which is the product of the resistance and capacitance.

🔌 The voltage across a capacitor in a DC circuit is 0 at t = 0, and it gradually increases as time passes.

💡 After a certain time constant, the voltage across the capacitor reaches 63.2% of the battery voltage.

⚡ The voltage across the resistor in a DC circuit decreases over time and approaches 0 as time goes to infinity.

💡 The discharge of a capacitor depends on the presence of a resistance.

🔋 Capacitors can be associated in series or parallel to obtain an equivalent capacitance.

⚡ Polarized capacitors can be associated in series with opposite polarities to obtain a non-polarized capacitor.
