My Question is 
  • what is conventional electricity?
  • why it is said that the direction of electric current is opposite to the direction of negative charges?

Expert Answer:

1. The electric current flows from a body at a higher potential (positive terminal) to a body at a lower potential (negative terminal), and this is called conventional electricity (current).
 

2. The actual flow of electrons is from negative to positive terminal of a cell. The electric current is due to the direction of flow of electrons in metals. Direction of the current is always from higher potential to lower potential. Negative terminal is at lower potential and positive terminal is at higher potential. Thus, the direction of flow of current in a circuit is opposite to the direction of flow of electrons (negative charge).
