First, we need to preface this by stating that amperage levels used in overseas countries does not match US amperage for the same items: electrical outlets, etc.
Second, watts, amps and volts differ.
The formula is:
Watts = Amps x Volts
We have missing pieces to know the amps and milliamperes (mA), which would help us in this question when sources say between 100 and 200 mA of current are lethal.
However, since 500,000 volts is a very large number, we can guess fairly well that this amount would be lethal.
It is important to note, though, that it is NOT simply the volts but other factors which determine what happens in an electrical shock.
AC (alternating current) and DC (direct current) differ also. A third part is resistance, which is not necessarily a fixed or constant variable. For example, muscle mass can be a resistance variable. As well, insulators would create a resistance variable. (As an example of insulators, in one shark movie, a female ocean scientist removes her wet suit and stands on it bundled up... plus she is wearing rubber soled shoes. She pulls a main conduit from overhead, which is sheathed in insulators with an outer metal covering...she can grasp the conduit because the insulator keeps the electricity within the conduit....and she's insulated herself through the rubber beneath her feet. However, had the broken end of the conduit touched her, anywhere, she could still have been electrocuted. Since the shark "fries" when he bites into the conduit, we can assume the volts and amps were high enough to cause the shark to "burn" through it's fat and muscles from the inside out. Because the volts and amps were high enough, the shark could not "let go" of the conduit. See below.)
Less alternating current (AC) will cause equal damage as direct current (DC).
A small amount of AC household current can muscle contraction. If the AC current is high enough, the person cannot let go of the source of the current. The value of the cut-off, i.e. when a person can physically let go of the source of the current, is known as the "let-go current". Depending on muscle mass, the 'let go" values are about 5 to 7 milliamperes for women and 7 to 9 milliamperes for men. Depending on the muscle mass and size of the person, the type of current, and other variables, 0.06 A to 0.07 A is generally lethal.
HOWEVER, even a small amount of electricity, even household electricity can cause severely harm or kill a human or animal ! This is due to several reasons. 1. The body has high water content, muscles, and fat which allow electrical current (not resist).
2. The heart, in particular, uses it's own "current" to contract the heart muscle. The heart must maintain a specific rhythm of contraction and relaxation to effectively pump blood to the lungs, brain, and other vital organs. So, when a human or animal experiences a low AC current jolt, it can cause the overall muscles to contract... and the outside current disrupts the body's normal cardiac rhythm. Even a low AC current can put the heart into fibrillation, which is kind of like shaking a bowl of jello... as long as the heart is fibrillating in the irregular fashion, the heart cannot return to its normal rhythm. If the voltage is high enough that the "let go" value is high, the heart has no possibility of recovering a rhythm. Even after the current is turned off, the heart will continue to fibrillate unless a "normal sinus rhythm" is established by external means, i.e. by a doctor, nurse, or paramedic using a "Defibrillator" machine to send a new low voltage "shock" into the heart back into a rhythm that is compatible with life.
Even in low voltage situations, other physical damage can be severe, including:
25 kilo-volts.
100 million volts
Those units describe different types of quantities, and the question is something likeasking "How many hours are in 15 gallons ?".When an electric current is consuming or dissipating 1,500 watts of power as it flowsfrom one point to another, then the number of amps of current is(1,500) divided by (the voltage between the two points) .
Amps * Volts = Watts. 50 Watts at 120 Volts = .4 Amps 50 Watts at 12 Volts = almost 4.25 Amps 50 Watts at 1 Volt = 50 Amps
the most powerful lightning bolt contains about 950 billion volts but it wouldn't be anything natural it would be the bolt that haarp discharges from the ionosphere of the earth vaporizing anything and anyone that sees it, and also everything around it for thousands of miles.
That depends on the total current flow and resistance of body at the time of contact.
Lets put a value to the transformer, say 500 VA. Step down with a 5:1 ratio. Say 250 volts on primary. 250/5 = 50 volts secondary. 500 VA transformer/50 volts secondary = 10 Amps. Therefore the secondary would have to have the larger wire to accommodate the larger current.
In the USA houses would have 120/240 volts. 120 volts at most receptacles and lights and 240 volts for larger equipment like your stove, dryer, hot water heater.
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
One would assume the chainsaw requires 120 volts or more if you want to run it with an inverter. If your chainsaw uses 16 amps at 120 volts then your wattage is Volts (120) x Amps (16) and that would be 1920 watts. So you will require a much larger inverter to run your chainsaw.
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.
No. 12 volts peak to peak would be 6 in the positive polarity and 6 negative polarity. Simply saying 12 volts AC would be 12 volts in each polarity or 24 volts peak to peak
No it would not.

To find the current, use the formula: Power (W) = Voltage (V) x Current (A). Rearrange the formula to solve for current: Current (A) = Power (W) / Voltage (V). Therefore, 160 watts divided by 120 volts equals 1.33 Amps.
Not everything needs to be. Many standard wire insulations are rated at 600 volts, some 300, and some are more or less. It would be cost-prohibitive to have everything rated at 480 volts. Especially things designed to operate at 120 volts. Things rated for 480 but running at 120 would be physically larger than necessary, and therefore more expensive. If you're wondering why everything doesn't just run at 480 it's because it's not safe for residential applications.
It depends upon the chemistry. Alkaline cells generate 1.5 Volts each, so six of them would yield 9 Volts, whereas six rechargeable cells would only yield 7.5 Volts, since each cell produces 1.25 Volts.
