Expert Answer:

Metals allow electricity to pass through them and are called conductors. The electric current is due to the direction of flow of electrons in metals. The actual flow of electrons is from negative to positive terminal of a cell. Direction of the current is always from higher potential to lower potential. 
An electrolyte consists of equally and oppositely charged ions (as a result of dissociation) both of which are capable of moving in a medium. This is a liquid state conductor in which electric current is due to the motion of both +ve and -ve ions. Ions move towards the oppositely charged electrodes.
