AC Fundamentals 241
AC Fundamentals 241 discusses alternating current (AC) as the most common form of electrical power. AC waves can be viewed and measured on the screen of an oscilloscope. Alternating current is economical, can be sent long distances, and can be stepped up or stepped down to adjust voltage. Different AC waveforms exist, the most common being sine waves. Ohm's law holds true for AC circuits, but voltage and current both increase and decrease together in a cycle while impedance remains constant.
Anyone working within electrical systems must understand the fundamental concepts and basic workings of alternating current to ensure their safety. After taking this course, students will be able to describe electrical flow in an alternating current circuit and the impact alternating current has on electrical variables.
