Answer 2

$\huge\b{Answer:}}$

ELECTRIC CURRENT AND ITS EFFECTS :

Electrical energy is the most useful form of energy as it can easily be converted into various other forms of energy such as heat energy, light energy, mechanical energy and chemical energy.

 

Electric current:

The flow of charges through a circuit is called electric current. The SI unit of electric current is ampere and donated by A. The direction of the electric current is conventionally from the positive terminal to the negative terminal of a cell.

Effects of electric current:

Now, according to Ohm's law, current is inversely proportional to resistance. Thus, the decrease in value of resistance of the circuit raises the current to a significant amount. As a result, the wires become hot and sparks are caused by Joule's heating effect of current.
