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 .
