Quote from: hamdani yusuf on 06/04/2023 08:47:13Jump starting gasoline cars is usually needed because of dead battery. It requires good condition of other components. It also requires high power. Normally, the engine is started using 12V car battery, and can draw current to hundreds of Amperes typically 400A, hence 4.8 kW is required. When the power is too low, it would be cooled down by the fuel and fail to ignite.When I couldn't afford a new starter battery, I used to start my old Skoda MB with a 12V dry battery temporarily attached to the ignition system. The starter battery only had to crank the motor over one or two revolutions before it picked up and the dynamo (pre-alternator days!) put some life back into it. Adding a diode in the "proper" supply line made it all very easy!

Incidentally the idea of encapsulating the HV generator in paraffin wax (candle wax) is a good one - makes life a lot safer and provides mechanical protection for the coil too. I built a 100 kV 10 mA unit about 50 years ago with a voltage multiplier inside a liter of paraffin wax, driven by a 20 kHz oscillator. Great fun!
In this experiment, we use a high voltage multiplier to supercharge a thick plastic bottle to the point where the charge can no longer be contained. The results are spectacular. The plastic of the bottle holds an incredible amount of charge towards the end of the experiment.
The outside of the bottle is negative. The inside of the bottle is positive. The net overall charge of the bottle with respect to earth ground is zero. The polarity could be determined by how it lights up a neon bulb. The negative terminal in a neon bulb containing two terminals would light up brighter than the positive terminal.
The experiment shows that positive electricity prefers the pointed electrode; negative electricity prefers the disk-shaped electrode. In the early days of X-ray technology, this effect was used to eliminate the closing current from a spark inductor and to supply only the opening current to the X-ray tube.
For Halloween, here is a quick look and electrical arcs and discharges, much like you often see in the old Frankenstein movies and the wonderful TV shows from the 60s like The Munsters and The Addams Family. Also included are many of the things we use sparks for in our everyday lives including spark plugs, lighting gas stoves, flash tubes, fluorescent lights, neon bulbs, and arc welding.
Influence is a consequence of the force effect between electrical charges. We explain and show what happens.
We show you what effect a tip and a ball have on PVC tubes which are charged with electrostatics.
In this experiment a high frequency high voltage diode is connected to the breakout point of a tesla coil to see if the Tesla coil will produce DC high voltage output instead of alternating current electric field .
Here is an interesting experiment that I am replicating from the JNL website. It is high voltage electrolysis that creates a an underwater plasma, but only on the negative electrode. It requires the use a asymmetrical electrodes, and I must admit, I can not explain the physics behind this phenomenon!? A very interesting video to say the least! Included is a link to the JNL webpage.http://jlnlabs.online.fr/cfr/ape/index.htm
The Asymmetrical Plasma Electrolysis (APE) is a simple experiment which can be easily performed with few material and uses a common lab equipement. This experiment will demonstrate you very easily that a glow discharge plasma can be observed on the CATHOD during an electrolysis process at a high voltage ( ~ 200 V DC ).This is the main process used during the high temperature plasma electrolysis (CFR) experiment from Tadahiko Mizuno from the university of Hokkaido in Japan.A similar experiment has also been performed by Renzo Mondaini (Italy).To conduct this experiment you need :1 auto-transformer (0-270V) 13A, 3.51 KVA1 circuit breaker (230V, 16A )2 diodes 400 V 5A1 capacitor 2200 ?F, 500V1 borrosilicate beaker ( 1000 mL )2 pure tugnsten rods (commonly used for TIG welding) 2 mm diameter 150 mm length400 mL of a solution of Potassium Carbonate (K2CO3) at 0.2 M

//www.youtube.com/watch?v=sDlZ-aY9GN4Why moving charges produce magnetic field?He asks an interesting question at around 14:45. Does magnetic field not exist at all? Is it only electric field and Coulomb's law?
We show you how dagerous propagating brush discharges could be.Welcome to episode 16 of our knowledge series "Basics of electrostatics". With this series we want to share our know how about electrostatics with you to make electrostatic applications safer.
there is wood chips from my garden in the water. The plasma is ignited on the water and attracts the wood chips in all directions.
Recently I found out that Rowland made experiment with rotating copper disc at high voltage which can move small magnetic needles. In other words, moving charged conductor produces magnetic field. Unfortunately I can't find the reference in Wikipedia. https://en.m.wikipedia.org/wiki/Henry_Augustus_RowlandIt's possible that the magnet simply moved due to Eddy current. If that's the case, removing the voltage should have no effect. I guess we can find out by replicating the experiment. I'm curious why it's not more widely known.
Making lightning is fun, and I built a Static electric gun to do just that. It can shoot static across the room, and also deliver a really serious charge.
