Describe Various Effects OF Current

Describe Various Effects oF Current:

Effects Of Current:
The present electric current can be detected by the various effects which are produced. Some effects of current are given below.

                          1.      Heating effects
                          2.      Magnetic effects
                          3.      chemical effects

1) Heating Effect:

current flows through the conductor due to the motion of free electrons. During the motion of free electrons, they collide with the atoms of metal. So, they lose their kinetic energy of the atoms is increased, Which produces heat in the wire.
If H is produced by a current I in the wire of the resistance R for the time interval t, then
                               H= IRT

Applications Of Heating Effect:

Heating effect of current is used in an electric heater, toaster and electric iron, Kettles etc.

2) Magnetic Effect:

When the current passes through the wire then a magnetic field is produced around it. The strength of the magnet field depends upon the magnitude of current and the distance from the current carrying conductor.

Application Of magnetic Effect

. Magnetic effect of current is used in the detection and measurement of current.

. All the machines involving electric motor also use the magnetic effect of current.

3) Chemical Effect:

There are certain liquids through which the electricity can pass due to some chemical reaction. The study of this process is called electrolysis.
This chemical effects of the current. It depends upon nature of the liquid and the quantity of electricity passed through liquids.

Application Of chemical Effect:

Chemical effect of current can be used for electroplating and purification of metals.

Electrolysis:

The process of chemical decomposition of an electrolyte due to flow of current, is called electrolysis.
