Introduction to Electrical Engineering and Circuit Analysis Videos - Introduction to Alternating Current for Circuit Analysis

In this video, Jitty introduces alternating current and explains how it differs from the previously learned concept of direct current. He explains what in-phase and out-of-phase means and shows you how to calculate the root mean squared (RMS) for voltage and current. The general formula for any alternating energy source and its variables are covered and the formulas for angular frequency are explained. Two practice problems are worked through to show how KVL, KCL, and Ohm's Law are used in alternating current circuits.
