1 of 1

Application +4 | -1

A current in a wire is given by the equation

I = 2{t^2} - 3t + 1

. The charge through cross section of wire in time interval

t = 3\,s\,\,\,{t_0}t = 5s

is

View answer and explanation

Correct option: B

43.34 L

Option B (43.34 L) is correct because it is the charge calculated by integrating the current function over the given time interval.
