Faraday's Laws VS Kirchoff's Rules
Description
The lecture brings out splendidly that Kirchoff's rules are only a special case of Faraday's laws.To explain Faraday's law concept of changing magnetic field inducing current is explained and demonstrated by passing current in a coil and moving a magnet near it.A solenoid experiment also verifies Faraday's law.When magnetic flux changes then the electric field in the wire is no longer conservative and depends on path. This is a concept which is rarely mentioned. In an UNBELIEVABLE experiment the potential difference between two points measured along two different paths is shown to be different.
