electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.

Explanation:

Electric current has the following effect :

(i) Electric current can give rise to heating and lighting.

(ii) Electric current can convert a straight conductor into a temporary magnet.

What is Electric Current ?

_____________________________________

$\Rightarrow$ Electric Current is the flow of Charge.

$\Rightarrow$The Continuous flow of electrons in an electric circuit is called an electric current.

$\Rightarrow$The Electric Current Direction is the direction which positive charge would move.

$\Rightarrow$Using Ohm's law, we can represent as the formula: I= RV.

What is Effects of Current ?

_____________________________________

$\Rightarrow$Magnetic Effect

It occurs in some devices like door bells.

$\Rightarrow$Heating Effect

when electricity passes through metallic wires with high resistance, this metals becomes hot and glow.

$\Rightarrow$Chemical Effect

Plating a layer of thin metal to another metal.

$\Rightarrow$Electrical Effect

Discharging electricity to the body, but in the level in which voltage is not much harmful.
