because it is 2 hot leads of 277vac =480v. not 2 hot leads of 110-120vac=220vac

The higher the voltage becomes the higher the current becomes through a set resistance.
A normal dry body's resistance from thumb to thumb is about 2.6 meg ohms.
This is the body's outside resistance from point to point and not the body's internal resistance. Once the shock has started the skin becomes burned and this starts to lower the outside body resistance to a lower value. The longer the burning continues the lower the outside resistance becomes until it reaches an inside body resistance.
The body's internal resistance is in the neighbourhood of 1000 ohms.
Using the same formula with the internal resistance and see the drastic current increase that will kill you.
The formula for amperage is Amps = Voltage / Resistance.
Using a secondary voltage of 220 the formula is, Amps = 220/2600000 = .0000846 amps or .0846 milliamps.
Using a secondary voltage of 220, the formula is , Amps = 220/1000 = .22 amps or 220 milliamps
Using a secondary voltage of 480 the formula is, Amps = 480/2600000 = .0001846 amps or .1846 milliamps.
Using a secondary voltage of 480, the formula is , Amps = 480/1000 = .48 amps or 480 milliamps
As you can see, as the voltage become higher so does the current that can flow through your body if you short across an electric potential.
The following list is the tolerances that the body can stand.
Less than 1/2 milliamp no sensation
1/2 to 2 milliamps Threshold of perception
2 to 10 milliamps muscular contraction
5 to 25 milliamps painful shock (may not be able to let go)
Over 25 milliamps Could be violent muscular contraction
50 to 100 milliamps Ventricular fibrillation
over 100 paralysis of breathing.

Alternating current is better than direct current for transmission.
Alternating current is more efficinent. It is wireless and more efficient than direct current. And it is safer. Plus Tesla is better than Edison
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
Current flow direction is not dependent on whether or not it's in a series or parallel circuit. Current directional flow is solely determined by the power source. For businesses and residential power, utilities use various forms of alternating current. For example, the United States utilizes alternating current that changes directional flow 60 times per second. Some parts of Europe use alternating current that changes direction 50 times per second. Many electronic devices use a direct current source in which the current flow is only in one direction, from negative to positive or a converter that changes the alternating current source power to direct current.
No, your universal alternating current direct current adapter will not mess up your electronic product. The rating that you find on the adapter is the maximum amount that you can draw from the device without damaging it. It is not like there is a surplus of current waiting to be used. The amount of current draw that it can produce is governed by the load demand. What you don't want to do is connect a device to the adapter that has a load higher that the rating of the adapter. Usually you can find the rating on the adapter rated in milli amps (ma) along with the output voltage. Also the load device will have what the amp draw is, also in milli amps.
Alternating current is better than direct current for transmission.
yes it is very harmful
Thomas Edison promoted direct current (DC) as the preferred method of electrical distribution. He believed DC was safer, cheaper, and more efficient than alternating current (AC) which was being championed by his rival, Nikola Tesla.
Alternating current is better than direct current for transmitting electricity over long distances because it can be easily converted to higher or lower voltages using transformers, which reduces energy loss during transmission. Additionally, alternating current can travel longer distances with less power loss compared to direct current.
Alternating current is more effective for long-distance travel than direct current because it can be easily converted to higher voltages, which reduces energy loss during transmission over long distances. This is due to the ability of alternating current to use transformers to increase voltage and decrease current, resulting in lower energy losses compared to direct current.
alternating current is easier to transfer long distances
Depending on how it's used, it can mean air conditioning, or it can mean alternating current (as electrically powered) as opposed to battery powered (DC, which is direct current). Or Animal Crossing
some things requre a dc (direct current) rather than an ac (alternating current)
Alternating current is more efficinent. It is wireless and more efficient than direct current. And it is safer. Plus Tesla is better than Edison
Alternating current is considered better than direct current because it can be easily transformed to higher or lower voltages, making it more efficient for long-distance power transmission. Additionally, AC allows for the use of transformers, which are essential for distributing electricity to homes and businesses.
No, it is the same. DC stands for direct current rather than AC, which is alternating current.
unfortunatley i cant tell for sure what you mean because of the lack of grammer (not insalting you) but if your asking wether it has direct current (DC) or alternating current (AC) like i think you are than the answer is direct current (DC)
