amps can kill?

Question

hiya people say its not the current that kills you but the amps......so if the voltage is 240v and the watts is 20 w please could someone tell me the ampage is and if this is enogh to kill you,

Thanks

Nasser

Answer 1

The unit of electrical current is the Ampere (or "Amp").
Amps measure current.
It isn't the voltage that kills, its the current.

At 240 volts and 20 watts, the resistance through the "circuit" can be found by rearranging this equation,
Power = (voltage)^2 / Resistance
Resistance = (voltage)^2 / Power
Resistance = (240 v)^2 / (20 watts)
Resistance = 2880 Ohms

From Ohm's Law,
V = RI,
the voltage and current are related by the resistance.
Solving for the current,
I = V / R
I = 240 volts / 2880 Ohms
I = .0833 amps (83.3 mA)

This is not a very high current, but it does not take much to kill you if it is directed through the right organs.

Answer 2

you sound like a very confused person about electricity. Amps are nothing but a unit of measure... units of measure don't kill anyone.
Amps are a way to measure current so when you say 1 amp that means 1 amp of current.
The formula for calculating curent is P=IV so in your case
20W=I*240V so I =20/240 =0.08 Amps.
Sure it doesn't take a lot of current to kill someone, but it depends on a lot of things like how well your body conducts, how good the grounding is between your feet and the ground , etc etc.
The batery from my car is 12V but it can deliver 600 amps. Touching it won't kill you.
the flash unit on a camera might be discharging 2000v or more, but the current is not all that high. Touching it could kill you, at the very least it will give you a nasty zap to remember for a long time.

Answer 3

Wattage = current x voltage. 20W/240V = 83mA.

This is a serious current to get hit with, and would be borderline fatal. Usually fatal shocks are between 100mA and 200 mA. Over 200mA causes severe burns, shock, and unconsciousness but rarely death.

83mA is going to cause serious pain no matter what. You dont want to get hit with it. The victim will not be able to let go if they are grabbing a hot wire. Your heartbeat may be affected. Risk of fatality would depend on where the current is going--extremities would be better than your head or your heart for example.

Answer 4

You wall outlet means is 120V and may be on a fifteen Amp circuit. in my view, with the age of the homestead fifty one' i does no longer bypass away the homestead unattended with that ingredient working. you're able to come homestead and nicely its a burning. As your residences wiring might no longer be as much as par. in case you extremely want to renowned what AMP you have bypass seem on the breaker panel. The breakers are marked 15,20,30 ect. so which you recognize the place you have it plugged in at, and on the breaker panel seem for breaker that serves the room / plug which you have the heater plugged into. If breaker says 15 on it you're able to be superb. in spite of the undeniable fact that, those heaters draw an incredible quantity of amps, so if for some reason the breaker keeps tripping its the two too vulnerable or your wiring it insufficient and is drawing too many amps (it too small of cord) and your risking a fire difficulty.

Answer 5

What kills you is the current and voltage. If you have a very high current but low voltage you can die or if you have a low current and very high voltage you can die. Obviously, if both are high you will die too. Things around 20 Volts can even kill you depending on your current like if you have wet hands. Currents of around 100mA can kill you as well.

Answer 6

Current is measured in amps.

So anyone who said that is a moron.

240V is residential single-phase 2-pole power. It usually won't kill you, as long as you aren't standing in a puddle of water, or grab ahold of a live wire and are unable to let go.

Answer 7

A very tiny amount of electric power can kill someone, only 1 watt applied to the heart can stop it and kill you.

1 watt is only 10 volts at 0.1 amp.

Hey brainiacs, just answer his question.
