Electric Current and Electric Circuit
Electric current is rate of flow of electric charge or the amount of charge flowing through a particular area in unit time.
- Until the discovery of electrons, the electric current was considered to be a flow of positive charge and the direction was considered from positive terminal of the battery to the negative terminal.
- In reality, electric current is flow of negatively charges particles called electrons. These flow from negative terminal of the battery to the positive terminal.
- As a convention, the direction of current is taken opposite to the direction of flow of electrons.
