magnetic effects of electric current
... Due to fault in the appliances or damage in the insulation of two wires, the circuit will offer zero or negligible resistance to the flow of current. Due to low resistance, large amount of current will flow. According to Joule’s law of heating effect (Ha I2) heat is produced in live wire and produce ...

... 3) The electric field just outside of a conductor must be perpendicular to the surface of the conductor. Again, what if this were not the case? Then a component of the electric field would exist along the conductor’s surface. This would yield an electrical force along the surface. As a good conduct ...
