Answer» The flow of electric charge is electric current. The charge of 1C consists 6.25×10^18 electrons.Now, total no. of electrons flowing per second is 62.5×10^18so, total quantity of charge flowing per second is (62.5×10^18)/(6.25×10^18)=10 CThe quantity of charge flowing per second gives value of current.since, 10 C of charge flows per second ,so, current is 10 A |
