Effects of Electric Current

Definition of current: Current is defined as the flow of charge per unit time.

that is I = q/t

There is flow of energy due to current called electrical energy. This energy can be converted into another forms and whenever there is conversion of electrical energy into another form of energy occurs then this conversion or transformation is called effect of electic current.

The following are the major effects of electric current:

  • Heating effects of electric current
  • Magnetic effect of electric current
  • Chemical effect of electric current

Let us discuss these effects one by one. Today we will discuss the heating effect of current:

When electric current flows through a resistor, it gets heated. This converion of electrical energy into heat energy results in the heating effects of current.

Following are the major reasons for this:

  • Current
  • Duation for which current passed
  • Nature of the substance through which current passed.

Applications of heating effects of curent:

All electrical heating instruments like electrical fuse, bulb, water heaters, electric heaters are the applications of heating effects of current.
