Problem

The current in a conductor varies with time according to

I = 4t + 2

, where

I

is in ampere and

t

in second. What is the total charge that passes through a cross-section of the conductor between

t = 0

and

t = 5\,\text{s}

? a)

55\,\text{C}

60\,\text{C}

40\,\text{C}

50\,\text{C}
