<p><span style="color: #000000;"><em><strong>we know that electricity is made of negatively charged electrons , so the electric current must flow from negative to positive as<span style="text-decoration: underline; color: #ff6600;"> negatively charge get attracted towards positive charge .</span></strong></em><span style="color: #333333;"><em><strong>&nbsp;but according to your information it flows from positive to negative so what is correct?</strong></em></span></span></p>

Expert Answer
In metallic conductors, free electrons are carriers of electricity and hence electrons constitute the electric current. Since electrons are negatively charged, they are attracted towards the positive terminal of the battery. Hence, direction of flow of electrons is always from negative to positive.
In an electric circuit, the direction of conventional current is always taken from the positive to negative terminal of the battery. 
Hence, the direction of conventional electric current is in the opposite direction of electron flow.
