induction motor

. Some of the important applications of eddy currents are: Electromagnetic damping, induction furnace, electromagnetic brakes, induction motor speedometers and in diathermy i.e., deep heat treatment of parts of human body. Some of the undesirable effects of eddy curren..

>The amount of heat generated in a conductor of resistance 'R', when current 'I' flows through it in a given time 't', is given by I 2 Rt. Electric power is said to be one watt if a potential difference of one volt causes a current of one ampere to flow through a conductor. The magnetic field insid..

An electric current produces a magnetic field A magnetic field exists in the region surrounding a magnet, in which the force of the magnet can be detected Field lines are used to represent a magnetic field The magnetic field lines of a straight current are circular with centres on the wi..

. It is an amazing fact that the charge carriers get this signal of direction change is propagated at the speed of light. What difference does it make if direct current flows or an alternating current flows in a conductor? As far as the heating effects are concerned such as light bulbs and heaters ..
