Electric Charge and Capacitors Concepts

This video tutorial covers electric charges, fields, and capacitors. It explains the properties of electric charges, how electric field lines are drawn, and the principles of Coulomb's Law. The tutorial also delves into the function and structure of capacitors, including their role in storing energy. Practical exercises and homework assignments are provided to reinforce the concepts learned.
