Mr. Physics Mentor

It has been experimentally seen that the resistance R of a wire is directly proportional to its length L and inversely proportional to its c...

We have seen that when a battery is connected across a conductor, an electric current begins.  How much current flows through the conductor ...

The presence of electric current can be detected by the various effects which it produces. The obvious effects of the current are: (i) Heati...

When two conductors at different potentials are joined by a metallic wire, current will flow through the wire. The current continues to flow...

An electric current is caused by the motion of electric charge.  If a net charge ∆Q passes through any cross section of a conductor in time ...

Electric Charge is the Intrinsic property of fundamental particles (like electrons, w bosons and quarks etc). OR   Electric charge is the in...

  Transmission of Electric Field  To describe the mechanism by which electric force is transmitted, Michael Faraday (1791-1867) introduced t...

  Baryons are strongly interacting particles having half-integral spins (1/2, 3/2, 5/2 . . . . .). A partial listing of some baryons is give...
