I. To recieve points, you must show all work and how it got to your answer.

II. Be sure to mention any constants.

III. Show how you derived any numbers that weren't originally given in the question.

Now, with the same logic...

If the instantaneous current through a heating element in a toaster reaches a maximum value of 6A to the left at some instant, what is the current through the element 1/240s later?
