my question is quite basic.. but still i lack behind in thinking...my question is that what generally current means.. we say its flow of electrons,charged particles... but how does this work?...what makes.. an electric..motor to run.. on passing current...how does it have such a powerful strength to run it? i have asked many of my friends... and teachers since 8th standard .. but still i haven't got the answer....plz explain something extraordinary about current in a simple language... so that my concept about it can be cleared.. thanku.. :-)

Expert Answer:

Current is indeed the flow of electrons/charges.
 
Whenever there is current passing through a conductor there are usually trillions and trillions of electrons flowing together through a small area of the conductor.
 
A small current like 0.1 μA will have 6.25 × 1011 electrons flowing through the conductor in one second.
 
These electrons together form a large enough current which enables daily appliances and even motor, to work.
