Alternating current delivered to a house comes on two wires. Let's call them line1 and line2. Electric charge flows in those wires, just as water flows in a river, and the current in a wire is …

Sep 28, 2024 · An ac source is one in which the current or voltage is changing in time in some periodic fashion, typically (but not necessarily) a sinusoidal wave. That said, in a circuit there …

What makes it a good idea to use RMS rather than peak values of current and voltage when we talk about or compute with AC signals.

Sep 17, 2016 · Why do we use AC (Alternating Current) for long distance transmission of electrical power? I know that AC is such a current that changes polarity (magnitude and …

Dec 11, 2021 · 4 I was eager to know why AC current has a smaller power loss than DC over long distances There is little difference between power losses for rms ac current at power …

3 In an alternating current, how are frequency, voltage, amperage, and watts related? For instance, imagining the power as a sine wave, what is amperage if voltage is the amplitude? Is …

However, AC's alternating nature has a greater tendency to throw the heart's pacemaker neurons into a condition of fibrillation, whereas DC tends to just make the heart stand still. Once the …

If electrons in an alternating current periodically reverse their direction, do they really flow? Won't they always come back to the same position?

Aug 29, 2022 · 0 Why is it harmonic in nature? I am starting to learn about alternating currents and somehow I can’t get the fact that it’s described by a sine wave and not by any complicated …

Dec 3, 2019 · It sounds as if you expect there to be some net movement of electrons in the "positive" direction in an AC circuit. But which direction is "positive?" Voltage is what makes …
