Solution

The current through a circuit element is given by the derivative of the net charge with respect to time. In this case, the net charge q is given by the equation q = 2t + t^2.

To find the current, we differentiate this equation with respect to time (t).

The derivative of 2t with respect to time is 2, and the derivative of t^2 with respect to time is 2t.

So, the current i = dq/dt = 2 + 2t.

This is the current through the circuit element in amperes.
