Inductor and its inductance

  Inductor and its inductance A current in a conductor produces a magnetic field surround it.   The strength of this field depends upon the value of current passing through the conductor. The direction of the magnetic field is found by using       Right hand grip rule which shown in the figure. If you hold the current carrying conductor by your right hand as shown in the figure the thumb shows the direction of current whereas the other four finger indicate the direction of magnetic flux lines Here the flux pattern for this magnetic field would be number of concentric circle perpendicular to the direction of current.      now if we wound the conductor in the form of a coil or solenoid it can be assumed that there will be concentric circular flux lines for each individual turn of the coil as shown but it is not possible practically as if concentric circular flux lines for each individual turn exist they will intersect each other however since ...

The Working Principle of Transformer

  The Working Principle of Transformer: A transformer is a machine but it does not have any moving part that is why a transformer is referred to as a static machine a transformer has three main parts, two windings and a metallic core on which the windings are wounded. windings are in the form of coil made of a good conductor of current the windings of the transformer play a main role in the machine the winding coils behave as an inductor when an alternating current is allowed to flow through any of the windings there will be an alternating flux produced surrounding the winding the magnitude of this flux is proportional to the magnitude of the current flowing through the winding the direction of the flux is according to the direction of current the direction of the current in the winding can be found out by applying right hand grip rule this rule states that when we grip our right hand with stretching the thumb along the axis of coil or winding and other four figures along the dir...
