Hi PM,



I'm reading the input power right from the Rigol power supply.  Why is that not an accurate way to determine the watts being consumed by the input?  That's why I purchased this power supply I was sick of figuring out my input watts.  The output is being read by the scope.  One probe is across a 0.1 ohm resistor set to 1x and 10x on the scope. Ohms Law measurement of: 1 x 0.1 x 10 = 1 Ohm. Meaning if you have 1 Volt measured across the 0.1 Ohm resistor it is 1 Amp, because 1 x 1 = 1.  The voltage is being read across the load.  If you watch the video to the end you see me put the scope on Averaging sample rate.  It still shows I'm getting more out than in.  If I'm not taking the readings correctly please advise.
Thanks,
Loz

It is easy to criticise others, without any viable or valid proof! Measurement error is the only excuse for some, it's how they explain things away, like UFO's being Swamp Gas, a laughable and truly disastrous excuse for any logical mind to accept as a logical answer.

Loz, I fully support you!

Anyone calling "measurement error" simply has sour grapes!

Best wishes, stay safe and well in these dire times,

Hope is good.
Good luck.

The PSU I use is a cheap Chinese made for $18.
Still, the performance is good.

Not 150W, it's 165W.
It is roughly correct to understand that cheap Chinese products are 80% efficient.

The French-Andre-Generator principle is,
The electricity amplified by spark gap-discharge is converted once again into magnetic DIY induction coil.
(Slightly modified tesla bifilar coil)
In order to make a stand-alone generator, more than four times the amount of current must be generated to create a stable self-supply system.
The Andre-generator is difficult to make standalone.
It is a generator less than four times the amount of current.

Ferrite DIY induction coil has an amplifying effect, but
The intention is to cut off the Tesla high voltage and convert it to a stable low voltage.
Ferrite DIY induction coil is a kind of transformer.

As a Ferrite DIY induction coil that converts from high voltage to low voltage, the DIY induction coil looks like the main, but in reality, the spark gap is the main.
The amplification effect in the DIY induction coil is insignificant.
220V/3A household power is supplied according to the power consumption.
This is mistaken for the amplification effect.
