It is true that high voltage light directly to eyes, can make someone feel dizzy.
I sent the electrician home.
Spark plugs don't produce high voltage they just make sparks with high voltage. The high voltage in a car is produced by running the low voltage of a car through a coil and condenser a distributor defines exactly when the spark happens to light up the fuel in the cylinder
This is strange, check the scale on your meter that you are reading, to make sure that you are on the correct voltage scale. If the reading is correct the suggestion would be to get an electrician to look into why there is such a voltage drop on the outlet. Don't read the voltage across the device, read the voltage from the "hot" wire to ground. That should be 120 volts. If you get that reading then there is a problem with the neutral. It could be loose or have a high resistive condition.

Answer for USA, Canada and countries running a 60 Hz supply service.Your house voltage most likely is not 300 volts. Just because you have a meter that tells you this is not proof. Many home owners have cheap volt meters that are not accurate. If you have an electrician friend or a friend of a friend ask them to check your test meter against theirs. I have done this for a few and have found out that the cheap meters do not hold calibration well. Once you have confirmed that your meter is accurate and the voltage is high, then get an electrician in to find out why. Depending on where the feed transformer is in relationship to your home might make a difference. If the transformer secondary line is a long one then the voltage at the transformer may be purposely set high to compensate for voltage drop for the homes connected at the end of the line. Most utility companies are mandated to keep the voltage within plus or minus 10 percent. With a base voltage of 230 volts this relates to high of 253 volts and a low of 207. These extremes are usually never used, with the average being about 245 as a high and 220 as a low.
I simple class I suppose would be shop. They teach you how to make a lamp so knowing how to make the light come on would be handy.
The high voltage does not make a humming sound. In fact, it is possible to create a high voltage line that does not make any sound. Still, you hear a sound. What you are hearing is the high voltage making something vibrate. In the United States it is vibrating at 60 cycles per second which is about A# 3 octaves below middle C. In Europe it is vibrating at 50 cycles per second which is about G# 3 octaves below middle C.
Nope, since Dubai is in a desert, but the government in Dubai COULD make artificial rain =P
It varries depending on where you live. If you are self employed you can make around $60 an hour, and as high as $100 ana hour in places with high demand.
as much as they make at maccas
If the voltage is fit, it will have no harm to your clients skin. Make sure you are using the high quality of tattoo power supply.
