Title: 1. Exercise charge, current

Example problem: Current

The charge flowing past a certain point in a wire is given by the following function:

[Image: figure of charge]

[Image: equation]

Determine

a) the current when t ≥ 0

b) the current at t =0

c) the time at which q(t) is maximum and the corresponding value of q

Example problem: Current

The charge flowing past a certain point in a wire is given by the following function:

[Image: solution question a)]

[Image: equation]

Determine

a) the current when t ≥ 0

b) the current at t =0

c) the time at which q(t) is maximum and the corresponding value of q

For the derivation we use the product rule. If you are not familiar with it anymore, it is recommended that you check again how it works.
