WATTS LAW EXPLAINED

Watts law explains the relationships between voltage, current, resistance, and power. There are three basic formulas that can be used. Each is explained in this video

Great video, using the different formulas to find the value

helpful video, wish you had used V instead of E for voltage just seems easier my Tafe Collage uses V they say E is outdated term. still helped me greatly once i worked that out , cheers

[@LonneLpp]

Agreed with V instead of E

[@toadamine]

Why dont you use V for volts, and C for current and such? It makes it much easier to remember P = V x C P = C² / R P = V² x R 🙋🤓👌

He doesn’t choose the variables… that’s how it’s supposed to be If he used V and C, whenever you’d see the actual formula using E and I you’d be lost

@@Davsoto120 🤣 I'd be lost using the letter that makes me remember its meaning easier? OK 🙄🤷‍♂️👌

Would be interesting to hear where you first heard the term "Watt's law" used to describe the power formula P = V I. James Watt worked with steam and mechanical implementations of power and did not do work or experimentation in electricity that I've ever heard of. He died about 8 years before Ohm published his work on what would eventually be called Ohm's law. While the unit of power, or really work is called the watt (W in SI units), it is formally defined with respect to the base SI units as kg * m^2 * S^-3, where '^' represents the raise to a power function. In other SI units it is represented as W = J/s. Therefore my belief is that it is inappropriate to refer to P = V I as Watt's law.
