The Fascinating World of Cylindrical Capacitors
Understanding Cylindrical Capacitors
A cylindrical capacitor of length 2.0 m consists of two concentric, conducting cylinders. The charge on the outer surface of the inner cylinder is positive (+50nC) and the charge on the inner surface of the outer cylinder is negative (−50nC).
The Beauty of Cylindrical Capacitors
A cylindrical capacitor is a fascinating physics device that stores electrical energy. It consists of two conducting cylinders with charges +Q and -Q, each having a length of 2m. The electric field is directed radially outward, and the enclosed charge is +Q.
Applications of Cylindrical Capacitors
Cylindrical capacitors have a wide range of applications in various fields. They are used for filtering static in radio reception, energy storage in heart defibrillators, and many other electrical systems where energy storage is crucial.
What is a cylindrical capacitor made of and how does it store electrical energy?
The question deals with a cylindrical capacitor consisting of two conducting cylinders with charges +Q and -Q. This physics device stores electrical energy and has a variety of applications. The enclosed charge is +Q and the electric field is directed radially outward.
Explanation: The question pertains to a cylindrical capacitor with two concentric, conducting cylinders. These cylinders have charges +Q and -Q on the inner and outer surfaces respectively. The capacitor is a device used for storing electrical energy. In a cylindrical capacitor, let's assume the cylinders have radii R1 for the inner cylinder and R2 for the outer cylinder with excess charges +Q and -Q residing on the inner and outer cylinders respectively. Each cylinder has a length of 2m as stated in your question. Calculating the capacitances of such capacitors assumes vacuum capacitors with no dielectric substance in the space between conductors. The electrical field between the shells is directed radially outward. From symmetry, the enclosed charge is +Q. A cylindrical capacitor can store charge and has applications ranging from filtering static from radio reception to energy storage in heart defibrillators.
