Why can you safley touch a 12v electricity supply but not a 230v mains supply?

When you have a fault you have a smaller flow of amps.
But calling it safer is misleading. It is my understanding that 110v kills more people every year than any other voltage because of people doing electrical work in their homes.

∙ 13y agoElectric current of 1 milliamp is barely noticeable. Current of 100 milliamps can be fatal, if it passes through the chest. The resistance of dry human skin can vary between 10,000 and 100,000 ohms. 12 volts can only push 1.2 mA through 10,000 ohms--that's completely harmless. 230 volts can push 23 mA through 10,000 ohms--that will hurt.
If the skin is broken or wet, the resistance of the skin can drop to 1,000 ohms. Under that condition, 12 volts can push 12 mA of current, which might be uncomfortable, but 230 volts can push 230 mA of current through the body, which could easily be deadly.

static electricity Static Electricity
Why if you touch positive terminal of the dc supply is not give shock?
If you touch one side and nothing else there is no path for a current to flow, therefore no shock. Don't try this with a supply of 50 v or more.
Why it is dangerous to touch anythings which work by electricity if your hands are wet?
Because u can get electricuted
Why are we advised not to touch life electrical appliances with wet hands?
Tap water and generally water (except specially proccessed water) can transmit electric current when the voltage is high enough. And the mains voltage (110 V for USA, 230 V for Europe) is more than high enough.
Why should you always be careful when using electricity?
dont touch with wety hand,dont use loose boards of electricity and also be used when reparing any cable also used gloves of electricity.
What should you do in an environment that promots static electricity?
you should use an ESD mat in conjunction with an ESD strap touch the metal case of the power supply that is plugged into a properly grounded outlet
Can you give 5 reported commands?
1. Mother said "do not touch the electricity, donna". = mother asked donna to dont touch the electricity.
What is a myth in electricity?
that u can touch urself with it
What is the difference between mains electricity and battery operated electricity?
Batteries range in output voltage from 1.2 volts for an AA rechargeable, to 12 volts for a car battery. There may be other voltages, for special purpose applications. Batteries supply DC (direct current), meaning that the current will only flow in one direction.What is considered "mains" electricity (from a plug or receptacle in the wall) is alternating current (the current is oscillating between flowing one direction, then the opposite direction then back and repeats). It oscillates at 50 or 60 times per second, depending on what country you live in. Also the voltage is between 100 volts and 250 volts, depending on the country, as well. These features enable the voltage to be changed up or down rather easily with transformer, and allow the electricity to be transmitted over long distances.But the alternating current and higher voltages also make your mains electricity much more dangerous to touch than a battery. A person's skin has pretty good resistance to electric flow, especially direct current. But with alternating current, if you touch a wire, charges can actually form under the skin and start flowing through your body, because your skin acts as a capacitor. Then, the oscillating current back and forth through your organs is much more damaging, possibly causing your heart to stop pumping.

How do you get the electricity out of your body?
Just touch a faucet in your house.
Do not touch the bulb connected to the mains?
it is because it may be very hot and your hand may burnt badly. you can also get an electric shock
Can you see or touch electricity?
You can see it in certain applications and physical phenomena.But you're always advised not to touch it.
What are the safety rules of electricity?
If you are not ABSOLUTLY sure - Don't touch it!
What do you have in a time machine?
in a time machine you have special gears and electricity. when the gears and the electricity touch it causes you to go to the future or the past.
