Current passing through a wire as function of time is given as $I (t) = 0.02 t + 0.01 A$ . The charge that will flow through the wire from $t = 1 s$ to $t = 2 s$ is :

Options:

Answer:

Solution:

$q = \int idt \int_{0}^{2} (0.02 t + 0.01) dt$

$q = [0.02 \frac{t ^{2}}{2} + 0.01 t]_{1}^{2} = 0.01 (3) + 0.01 (1) = 0.04 C$
