Your show is purely educational and I enjoy it. Thank you. I am sorry if basic educational knowledge is not making you rich yet. Keep at it. Everyone benefits.
Not correct for AC. From Wikipedia, for ex. :: Ohm's law holds for circuits containing only resistive elements (no capacitances or inductances) for all forms of driving voltage or current, regardless of whether the driving voltage or current is constant (DC) or time-varying such as AC. At any instant of time Ohm's law is valid for such circuits...... this means it could be correct on any given time as short as possible, but not continuously. Remember, AC in your outlet is of the sine form.
Was also going to add, assuming your voltage is 120V is just an assumption. Depending on what you are really trying to find out that assumption might be ok. But consider this.. if the actual voltage is 125V the amps measured will be higher than if it's 115V, or even 120V. Which voltage at the outlet does vary. For the person along about measuring the power without a clamp. ONLY if it's a purly resistance load, like a heater or an incandescent light bulb: You can measure the resistance (ohms) then use V=IxR or I=V/R, then having calculated the amperage you can find the power. ONLY on resistive loads.
Tx, it's helping, every little bit does. Is there a method without the clamp for a specific situation? All I need to do is confirm the led fixtures I buy online from China are actually what they claim them to be, cz most are not. Can't really afford a clamp meter right now. Any ideas? ...p.s. I have a decent, standard multimeter. I tried leaving the lamp half plugged and touched the blades with the probes, lol, you probably know that didn't go well, haha
I have that exact clamp multimeter and ready product of the name voltcraft 4000 pro designed especially for power usage readings. But my readings are different - which device should I trust? Both producents claim that meters are accurate but at least one is BSing I suppose

Hehe thanks for the kind words! It is quite good compensation getting comments like yours though!
Great job. Simple but done well!!

Great video and very simple ty
Very good explanation 👍

What about inductive load
thank you good sir

Why we take the main grid volt 120 v as volt? I thought inside the devices some voltage regulator changes the volt
It does, but you pay for what comes out of the wall
when the volts go down, the amps go up
Can you show us device that measures how much washing mashine consumes power from wall plug. I also want to measure for entire month.

Test a known current, do you have an adjustable power supply?
@@SimpleElectronics sadly no, wish I had tho
Any standard resistors?
Does this work for 220 V appliances like ACs?
Yes but it may not be needed, try it directly first!
