With clear concepts, symmetry-based thinking, and smart circuit practice, Electrostatics and Current Electricity offer a ...

In this video, we use Gauss’s law to find the electric field of a uniformly charged sphere. We derive the field both inside and outside the sphere, explain the symmetry behind the Gaussian surface ...

How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits. The quantum-mechanical processes that enable the ...
