AC/DC what's the difference?



Students will be introduced to the theory behind the two sources of electrical power. They will be given a chance to build on prior knowledge of direct current circuits and then expand that knowledge to include the workings of alternating current circuits. This lesson will provide a base for understanding direct current circuits the remainder of the year.
