What are some deadly facts about electricity?

Answer 1

When electricity enters your body it contracts your muscles, causing you to suffocate.

It takes three things for you to be electrocuted:

1. amount of current - as little as 50 mA can kill

2. path of current - current through one finger and out another is usually not fatal, but current through your chest can be

3. duration - the longer you are part of the circuit, the greater your chances of dieing

Enough current through your chest will cause your heart to go into fibrillation, restrict breathing, or cause internal organ burns. If enough current travels through one of your limbs and exits without going into your chest, a portion or all of that limb could be blown off and then you could die from shock.

Another danger is arc blast and and arc flash, which occur when there is a short circuit. The flash can be hotter than the sun, causing burns to large portions of your body. The arc blast is the pressure wave that is released when the electrical equipment explodes, enough pressure to put you deaf and collapse your lungs.

All electrical work can be extremely dangerous if the person doing the work is not qualified.

The National Electrical Code defines a "qualified person" as "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."

For your own safety, call a qualified licensed electrician.

**Note#1: If you don't want to read a detailed explanation of electricity, skip down to the last paragraph**

**Note#2: This is just a "brief" explanation of electricity, so if I don't explain what you are wanting to know...than ask again or Google it**

Electricity, much like anything else has many different parts to it; voltage (V or aka E), current (I), resistance (R), and wattage/power (P). All of these factors have to be accounted for, before being able to answer your question.

The best way to descried electricity is...a dam holding back water. The water is the voltage, the dam is the resistance, the water flowing out of a pipe is the current, and a water wheel is the wattage/power; or how much work its done. If a dam is holding back water than no work is being done, nor is any current flowing. Like water, if the voltage isn't moving its not doing anything. Now, if we add a drain pipe to the dam with a flow meter on it, the water will start moving and creating "current" and we can measure the "current" using the flow meter; which in electricity terms would be a multimeter. If water is moving, but isn't moving anything it really isn't doing any "work". That's where the water wheel comes in. Depending on the current, voltage, and resistance will depend on how much the wheel will turn, thus creating work. I'm not gonna go into the math about it, but you get the picture.

With this knowledge, a person can say that 20,000 volts might be less deadly than 110 volts. For example (in dam terms), if the dam is holding back 1,000,000,000 gallons of water, but only letting about .5 gallons an hour pour out, than we can all agree that that's not gonna do much; yet if we had a dam holding 10,000 gallons of water with a drain pipe allowing 100 gallons a minute pour out...that might be deadly. An American house hold wall outlet puts out about 110V, yet static electricity puts out about 20,000V per inch. Not many people have died from static shock, but a lot have died from being shocked by a wall outlet. IT MOSTLY HAS TO DO WITH THE CURRENT!

Now you might be asking yourself,"Well, how much current CAN kill a person?", and the answer is...Google it....... lol jk I'm not gonna just leave everyone hanging like that. The answer is around 50mA across the heart; which is .05Amps or 5% of a real number. I hope this explanation has answered your question. Have a nice day. :D

Answer 3

Only closed circuits work

Lightbulbs get dimmer if you add another lightbulb on the circuit

Lightbulbs get brighter if you add a more powerful battery

Things that can't conduct electricity are called insulaters

Things that can conduct electricity is called electricity conductors
