As we learnt
Total charge flowing -
- wherein
Total charge
Let dq be the charge which has passed in a small interval of time dt,
then dq = idt = (4 + 2t)dt
Hence total charge passed between interval t = 2 sec and t = 6 sec
q = = 48 coulomb
Option 1)
60 coulomb
Option 2)
24coulomb
Option 3)
48 coulomb
Option 4)
30 coulomb
