Will a high voltage dc battery/supply that does not have an earth connection give a shock through ea]]>

A lot of people, including me, use an example like this to show how a sine and cosine can form a rotation. I believe this to be misleading.

Both the sine or cosine alone are rotations. The only thing we see in that gif, is the sine, or the cosine, but not both. To see the cosine........you would have to go up to the north pole of the sine and look down. Then you could see the cosine. It lies in the x plane.

The sine is like the...

Spherical Resonance Theory]]>

The first problem of understanding the difference, is the mis-used term "alternating current". A true alternating current would come from a square alternation. A true on-off, steady constant current, alternation.

AC/DC CURRENT]]>

When we take a current pi from an element, we leave a positive electric pole at the end and a negative electric pole at the feed point. This leaves an electric gradient along the element. During this charge separation, we...

Emission Mechanics]]>

Could this be wrong? Is linear length equal to angular length? Is linear time equal to angular time? Are we comparing linear momentum to angular momentum in the correct manner? Can we compare linear velocity to angular velocity?

Do we even know the fundamentals?

Here is the experiment....

Does Momentum or Motion Change Pi?]]>

Dear all,

First thanks for taking the time to read this, I really appreciate it.

Let me briefly introduce myself. I'm a high school student who's trying to make an automated cloud chamber, no dry ice. After a lot of hard work, we ended with what you see in the provided images, but when we turn the system on we are unable to see any tracks, while you can see a clear cloud forming.

I'll briefly explain how it works, in the bottom you have a big refrigerator recycled...

Why am I not seeing tracks in my cloud chamber?]]>

I'm an amateur biodiesel enthusiast

I want to increase the agitation between triglycerides and methanol to produce fatty acid methyl esters and want to use an ultrasonic transducer to do this.

I have seen successful test batch reactions in ultrasonic cleaners and wanted some advice on optimising the process.

Does the frequency/wattage need to be optimised to the size of the vessel in which the reactants are mixed?

Does the frequency/wattage need to be optimised to the viscocity (or...

My response was that the permeability of free space (an empty vacuum) is optimum for the electric field component rather than for the magnetic component which requires permeability similar to iron or an other ferrous material.

Since a vacuum has excellent permeability for the electric field, but poor...

Question About Antennas For Transmitting Electromagnetic Waves]]>

I have been studying the behavior of the potential in an electric dipole aligned to the Cartesian coordinates (x,y,z). These equations were obtained from said derivation:

Now, I am not an avid MATLAB user and I need a code that implements each of these cases into functions that can be input to MATLAB in the Y-Z (90deg) plane. I know that the command 'gradient' is used to compute the electric field and that 'contour' and...

Please look at three attachments. I want to know the minus/plus sign of induced voltage of each rotor segment. Like in file no.3, equation 4-19, why (vxB)•l is not equal to eab instead?

Relevant equations

equation 4-19 and 1-45

Thanks
