In the video you will see a guy experimenting with resistors and capacitors. what he shows clearly is, that we can make use of reactive power for resistive loads! brillant demo and setup - enjoy!

Hey Baerndorfer,
Great Vid! Thanks for sharing!
I have added some data for downloading BLOB Videos in the thread: Help with using the Forum.
Its not easy, but not too bad if you have a good grasp on IT. If you need help, let me know! Happy to help!
FYI: The voice in the video, sounds like user: GotoLuc, not sure if it is or not.
Best Wishes,
Chris
today i did a replication of the reactive power 'effect' which is described in the video above.
this is how it looks on the bench.
the energy comes from grid (isolation transformer / AC 50Hz 230V) - this is the gray cable on bottom.
brown is hot wire (phase), blue is neutral. the voltage is monitored on CH1 (yellow). oszilloscope ground is neutral.
the phase is connected to one side of capacitor (50uF) and the other side of capacitor goes to the load (0.1Ohm resistor, 50W). the voltage that is dissipating on the load is monitored by CH3 (pink).
i have CH2 (blue) to check the current which travels through the circuit. the voltage drop on the SHUNT (2x 0.1Ohm, 50W in parallel) is used to do some math on the oscilloscope.
not lets have a look at the situation on the load.
i have 2 MATH-functions on my scope and i use MATH2 for monitoring the power dissipation on load. voltage (CH3) and current (CH2) multiplied by scope-function (RMS value) - we can see 2,7W happening.
now we should have a look at the net-consumption.
we can see a Phase angle of 90,xx° (this is important to have!)
the scope can calculate the Real Power based on voltage, current and phase angle.
have a nice day!
Hi,
Thanks for experimenting too! I did a similar test with 10ohm load as in the original video, tested actually various capacitors and loads. Unfortunately did not find anything special.
On my scope I have the calculated watts line (MATH) and the average value of it as a digit that reflects the reality - the same that is consumed from the grid is dissipated on the load. [headbang]
This watts line is required to zoom properly (normalize), so then it starts to show more realistic values, especially when you are testing in a low power range.
In your case I see the reactive power is 848VA and the power back to the grid is -3.31W. This is proportionally only 0.4%, thus probably below the measurement capability. And the phase angle calculation is also not working when waves are not sinewaves anymore, I have found that too in the experiments when phase angle goes over 90 degrees - I wish it goes, but power measurement does not reveal it.
Try it with around 10ohm load (and properly calculating the watts so that it won't bang).

In physics, scalars are physical quantities that are unaffected by changes to a vector space basis. Scalars are often accompanied by units of measurement, as in "10 cm". Examples of scalar quantities are mass, distance, charge, volume, time, speed, and the magnitude of physical vectors in general.
You need to forget the Non-Sense that some spout with out knowing the actual Definition of the word Scalar! Some people talk absolute Bull Sh*t!
The pressure P in the formula P = pgh, pgh is a scalar that tells you the amount of this squashing force per unit area in a fluid.
A Scalar, having both direction and magnitude, can be anything! The Magnetic Field, a Charge moving, yet some Numb Nuts think it means Magic Science!

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
