In this video, we derive the electric field between two charged plates using fundamental principles of electrostatics. Step-by-step reasoning, clear equations, and physical intuition are used to show ...
Kauai, one of the most remote islands of Hawaii, stands steady among the timeless crash of ocean waves. Electric waves, however, almost crashed Kauai's power system in an instant.
Until now, it has been widely believed that wires are necessary to transmit electricity from one place to another.
