Transcript

• [Voiceover] We now begin a whole new area of circuit analysis called sinusoidal steady state analysis. You can also call it AC analysis. AC stands for alternating current. It means it is a voltage or a current that where the signal actually changes sign. It is positive sometimes. It is negative sometimes. And the conventional name for that is AC ... Read More
