No? Ask those electrocuted in the electric chair.
Our body is 70% water and with enough current intensity it will boil and evaporate. If the current is DC, the water will also separate into H and O (electrolysis) in the process.
The result is charred flesh.
Do not even think in playing with electricity. It will kill you or whomever is around you.

∙ 12y agoElectrical wires heat due to the resistance in the wire. Wires have low but not zero resistance. The metal bars of a radiator heat and glow red hot as they are designed to have high resistance. The resistance is due to the electrons having to travel along the wire and impurities get in their way. The bigger the cross sectional area of the wire the lower its resistance and the less heat. Filament lamps have a very fine wire to increase the resistance.

Heat energy is transferred from the hot end of a metal wire to the cool end through?
Heat conduction, by means of particle collisions transferring energy.
What wire size is needed for 60 gallon hot water tank?
10 awg
What is the reason that a cold magnet is stronger than a hot or room temperature magnet?
A cold magnet attracts more than a hot magnet. This helps the flow of electricity which therefore helps the electric field, which therefore helps the magnetic field. They use cold magnets to power the LHC which collides hydrogen atoms. Obviously the cold magnet is very attracting.
How to wire a 5 wire thermostat properly without a diagram?
depends on whether thermo used on gas or elec. unit, heat pump, strip heat, etc. red wire is hot wire. White wire goes to heat. yellow wire goes to outdoor unit contactor. green wire goes to indoor fan. blue or brown wire goes to reversing valve on outdoor unit.
What is the science knowledge involved in how toasters work?
It's all Physics. The basic fact is that when you pass enough electricity through Nichrome wire it will get hot from its electrical resistance . Also different toasting levels take different heat and/or time to accomplish.
How does a hot wire emit electrons?
a hot wire emits electrons just like any other wire would. It is through the flow of electricity. Its the exact same thing. Good question though
Why does a wire become warmer when a charge is flowing through it?
Because the electrons in it are moving about. This is similar to what happens when you run about, you become 'hot'.
How does electricity flow through a light bulb?
The atoms inside the wire of the lightbulb all have electrons which are pushed from atom to atom when the light is turned on, this is the current. When the electrons are pushed around the circuit they generate lots of heat because the wire in the bulb is so thin, this makes the wire glow white hot which creates the light.
How are batteries connected in a flashlight?
The electrons from the battery go through the wiring to the bulb. Inside the bulb, they heat a tungsten wire so hot that it glows, giving off light.
What characteristics of metals contribute to their ability to conduct electricity?
In covalent compounds the electrons are bonded to the atoms, so they cannot move outside the molecule. When ionic compounds like NaCl are dissolved in water, they produce positive and negative ions that can be attracted to the opposite terminal of a battery, so electrons flow off of the negative ions thru the wiring, thru the light bulb and back into the salt water and onto the positive ions. [Click on the related link to see the image] The circle with a wave inside represents a battery. In metals like Al and Cu, the electrons are not bonded to one molecule. They are free to move all around the wire. If you were to take the same light bulb, battery and electrodes and use a copper wire to connect the electrodes, the bulb would light. The voltage of the battery forces electrons on one end of the wire. This produces more electrons than protons in the metal wire. Since the electrons are free to move, electrons will move off the other end of the wire and thru the bulb, causing the wire filament in the bulb to get so hot that it glows.
Why does a piece of wire become hot when it is bent repeatedly at the same point?
friction of the electrons are not moving freely in the wire, they bump on each other
What is the link between the thickness of the wire and the current needed to melt a wire?
Well, I am also doing this same question and its all about resistance. Resistance is when the electrons flow around a circuit and they collide with ions. These electrons transfer energy to the ions, which consequently get hot and move more so the resistance increases :) So the thicker the wire is, the less resistance it would have because there are more choices of pathways for the electrons can take without colliding with the ions. Therefore less resistance, more current needed to melt the wire. So the thicker the wire is, the more current is needed to melt it
Where can a hot wire cutter be bought?
One can purchase a hot wire cutter through various stores that sell electrical appliances. There are equally some online stores that sell hot wire cutter like, amazon.
What happens if you connect a short copper wire to both the positive and negative terminals of a battery and why?
The wire will get hot, the temperature it gets up to will depend on the ampere of the battery and size of wire. The wire can get hot enough to causes burns or start a fire if the battery is large enough. Why this happens is because you have shorted the battery out. The power comes out of the positive post and back in the negative post. When you short it out the power can flow from one post to the other very quickly causing the short to get hot, due to the amount of flow.
What will happen to an electric wire if a large current passes through it?
It will get hot.
What conditions are necessary for a magnetic field to produce a force on a wire?
To answer this question, let's look at the definition of the following words. Voltage, Current, and Resistance One volt is one joule of energy per coulomb of electrons. One ampere means one coulomb of electrons is moving through the wire each second. R = V ÷ I = J/s ÷ C/s = J/C The resistance measures the amount of energy that is required to make one coulomb of electrons move through the wire. The charge of one electron is 1.6 * 10^-19 C. To determine the number of electrons per coulomb, invert this number. Number of electrons per coulomb = 6.25 * 10^18 One ampere means 6.25 * 10^18 electrons are moving through the wire and resistor each second. If the resistor is one ohm, one volt will be required for this to happen. To determine the amount of charge that is moving in a wire each second, you will need to wire's resistance and the voltage that is being used. Voltage and resistance determine the amount of charge that is moving through the wire each second. I hope this answers your question.
When too much current flows through a wire it can cause?
the wire will burn red hot or desinigrate instantly
