Volts, Amps, Watts - What Exactly Do They Mean??

Ever wonder what the electrical terms of volts, amps and watts mean? In this video I do a little teaching to help you understand a little more about electrical theory.
And we'll do some practical measurements and testing using a digital clamp/multimeter.
This is an excellent meter for a great price:

Other videos use confusing diagrams and technical terms I don't understand. This is by far the best video explaining everything. I hope others find this video as helpful as I do.

I loved your water analogy. I used to use electrical analogy when I taught cardiac heart rhythms, which is basically plumbing and electrical. Great video.

@@theinternetelectrician VOLTS = Water Pressure (50 psi)? AMPS = Water Flow Rate (ie. gallons per hour)? WATTS = Water Used (ie. gallons)? Volts x Amps = Watts? Water pressure multiply Flow Rate equals Water Usage? 50 psi x 1 gph (mist nozzle setting) = 1 g 50 psi x 2 gph (shower nozzle setting) = 2 g 50 psi x 4 gph (full nozzle setting) = 4 g Notice the gph always equals the final amount used. WATER: If 1 gallon of water flows passed (AMPS) a given point ("switch/valve") per hour then after one hour the bucket will have just one gallon of water (WATT?). But apparently in the world of electricity, AMPS and WATTS are NOT measured equally. So, why aren't AMPS (amount of electricity flowing passed a given point) equal to WATTS (amount of electricity used/expended)? What is the difference between AMPS and WATTS? What is the advantage of having two different names to measure electricity whether it is flowing versus after it is used? If the amount of electricity that ends up getting used varies from the amount of electricity that passed the "switch", what causes that variable? In WATER, regardless of the water pressure, if a nozzle/fixture/outlet (load/appliance) restricts the amount of water used to X per hour then the rate at which that water is flowing passed the valve will be equivalent to what ends up in the bucket. It would be weird if the water flow rate was say, 1 gallon an hour but we measured 2 gallons or only half a gallon in the bucket. Either the instrument used to measure the flow rate is broken or the water in the bucket was not measured correctly. Forgive my ignorance.

@@Christian_Prepper the end device (nozzle, sprinkler head, or the electrical load) is what determines the flow. The more restriction (resistance) the less current (water) will flow. With nothing on the end of the hose (or a solid connection to neutral or ground, large amounts will flow, regulated only by the supply and in the case of electrical, the breaker will trip. In the case with water, the yard or house will flood. Does that help?

Interesting video Terry. I taught a few hundred Computer techs in my life and always used a water analogy. I think you could have explained it much better with a good graphic. Give me a bit, If I can come up with one, I will send it to you.

The big difference between the water company and the electric company is the water company sends the water out and does not want it back. The electric company always wants their electrons back.

Yeah, and then they re-sell them! Actually water does come back. The water cycle. Cannot be created or destroyed.

That variable is very tough to nail down. We used to use 10c as a baseline. "Back when I was a kid"!
