@ sree , 
The electric current  can be defined as the flow of electrons per unit area , 
but when u are talking abt electricity , then its actually a sum total of many branches of current suming total . 
Electricity have a very wide well known effect such as lightening , charge transfer , etc . 

ITS A PHYSICAL PHENOMENA . 
the unit of electric current (defined above ) is ampere .
