Question

An electric applying draws current of 0.4 Amper . when the voltage is 200 volt.calculate the amount of charge. following in 1 hours.

Answer 1

since current(I)=charge(Q)/time(t)

therefore 0.5=Q/3600  [since 1 hour=3600 sec]

therefore Q=0.5*3600
...
Q=1800 couloumbs

Answer 2

hope it is helpful for you
