This tutorial will test your understanding of Kirchhoff's Voltage Law (KVL), Kirchhoff's Current Law (KCL), and Ohm's Law. All the circuits in this tutorial can be solved "in your head", but writing down a few loop equations and node equations couldn't hurt. There are a lot of "distractors" -- circuit elements that do not contribute to the solution.
Find the current I. Give your answer in amps.
