What is the difference between electric current and electric charge?
Your question is very broad. The first thing. No they are not the same. Simple explanation for these terms can be:
Charge: Its the "amount" of unbalanced electricity in a body.  Its usually measured in the form of electrons (either excess or deficiency). Its units is coulomb.
Current: It is the "flow" of electrons from higher electric potential towards the lower. Its unit is ampere. 

To visualize how they are not the same is by considering two situations (without going into any calculations). Two bodies (A &amp; B) are connected via some copper wire. A has 1 million Coulombs charge &amp; the second one has 1million &amp; 1 coulombs charge. Now individually these charges are enormous, but as the difference between the two is only 1 coulomb, its a very low difference in charge, so a little current will flow between them.

Now if you change the bodies' charge. A has 100 Coulombs &amp; B has 10 .. much more current will flow between the bodies, because there is a way bigger potential difference. 

ps. and yes its a physics questions.
