**Q: What is capacitance?**


Capacitance is a measure of an electrical component's ability to store electric charge. It is defined as the ratio of the electric charge (\(Q\)) stored on a conductor to the potential difference (\(V\)) across the conductor.


**Q: What is the unit of capacitance?**


The unit of capacitance is the farad (F), named after Michael Faraday. One farad is equivalent to one coulomb of charge stored per volt of potential difference.


**Q: How is capacitance calculated?**


Capacitance (\(C\)) is calculated using the formula \(C = \frac{Q}{V}\), where \(Q\) is the electric charge stored on the conductor, and \(V\) is the potential difference across the conductor.


**Q: What factors affect the capacitance of a capacitor?**


The capacitance of a capacitor depends on its physical characteristics, such as the surface area of its plates, the distance between the plates (dielectric thickness), and the properties of the dielectric material between the plates.


**Q: How does capacitance contribute to electronic circuits?**


Capacitance is essential in electronic circuits for storing and releasing electrical energy. Capacitors are widely used to filter signals, smooth power supplies, and control the timing of circuits. They play a crucial role in various electronic devices and systems.

What is work ?

 In physics, work is defined as the product of force and displacement in the direction of the force. Mathematically, it's represented as: W=Fd Where: - \( W \) = Work done - \( F \) = Force applied - \( d \) = Displacement - \( \theta \) = Angle between the force vector and the displacement vector

Parallel capacitor

 **Q: What is a parallel capacitor configuration?** **A:** A parallel capacitor configuration is when two or more capacitors are connected side by side, sharing the same voltage across their terminals. **Q: How is the total capacitance affected when capacitors are connected in parallel?** **A:** When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances. Mathematically, \(C_{\text{total}} = C_1 + C_2 + \ldots\). **Q: What advantage does connecting capacitors in parallel offer?** **A:** Connecting capacitors in parallel increases the overall capacitance in the circuit. This is useful when a higher capacitance value is needed, providing more charge storage capacity. **Q: How does the voltage distribution work in parallel capacitors?** **A:** In a parallel capacitor configuration, each capacitor experiences the same voltage as the voltage across the entire parallel combination. This is because the voltage across elements in parallel is const

Endocytosis and exocytosis

 Endocytosis and exocytosis Q: What is endocytosis? A: Endocytosis is a cellular process where the cell engulfs external material by wrapping its cell membrane around it, forming a vesicle. Q: Differentiate between phagocytosis and pinocytosis in endocytosis. A: Phagocytosis involves the engulfing of solid particles, while pinocytosis involves the engulfing of liquid or small particles into vesicles. Q: What is the role of receptor-mediated endocytosis? A: Receptor-mediated endocytosis is a highly specific form of endocytosis where substances bind to receptors on the cell membrane, triggering their uptake into the cell. Q: How does exocytosis differ from endocytosis? A: Exocytosis involves the expulsion of material from the cell by fusing vesicles with the cell membrane, while endocytosis is the uptake of material by the cell through vesicle formation. Q: Provide an example of a biological process involving endocytosis. A: The uptake of cholesterol by cells through receptor-mediated en
