RMS Voltage Explained | How to Use RMS Voltage [AC and DC Circuits]

What is RMS voltage and why do we use it? How to derive the formula for RMS voltage? Rms voltage allows us to compare AC and DC circuits. This video explains what RMS voltage is, and why it is used. This video will also show you clearly, step-by-step how to derive the equation for RMS voltage.

He wasn't kidding when he said this was the best and most clear explanation of RMS voltage anywhere on the internet

Sure, could sit through all the math and what have you, but the truth of the matter is electricians almost always use the RMS values is because it represents the same amount of power consumed in a purely resistive load on a given DC voltage. An example here, let's say I'm out traveling in the wilderness where no utility supplied electricity is available, and I have a simple coffee maker with an ON/OFF switch that's rated 840 watts, 120VAC, 7A. Lets assume I don't have a power inverter to connect to my car battery, but I happen to have 10 large 12 volt batteries, so I decide to connect them in series to get 120VDC, and rig up my coffee maker to them for my much needed shot of caffeine. In this scenario the coffee maker would consume 7A , 840 watt just as if I were using it at home with my wife and kids.
