What happens when you get electrocuted by a power line?
When you get electrocuted by a power line, the electrical current can pass through your body, causing serious injury or even death. The high voltage can disrupt the normal functioning of your heart and other vital organs, leading to cardiac arrest or severe burns. It is important to stay away from power lines and always seek help from professionals if you encounter a situation involving electrical hazards.
What happens if you touch a power line and how dangerous is it?
If you touch a power line, you can get electrocuted, which means you could suffer severe injuries or even die. Power lines carry high voltage electricity, which can cause burns, cardiac arrest, and other serious health problems. It is extremely dangerous to touch a power line and should be avoided at all costs.
What happens to a person who hangs on the power line?
If a person is simply hanging from the power line, not touching anything else, nothing much will happen. This is also the reason why birds can sit on power lines, and squirrels can run along them without injury. However, if the person hanging form the power line completes a circuit by touching anyhting through which current can flow, that person will be electrocuted and may not survive the experience. Items that could be touched and cause electrocution include vehicles, ladders, power poles, trees and shrubs, kite strings, other power lines operating at different voltage, among other things.
What is the formula for calculating power loss in a transmission line?
The formula for calculating power loss in a transmission line is Ploss I2 R, where Ploss is the power loss in watts, I is the current flowing through the line in amperes, and R is the resistance of the line in ohms.
How much power can a transmission line carry example how much power can a 69kv line carry compared to a 390kv line what is the formula for power capacity of a hvac line?
For a line of given cross section and material, the power capacity will depend on the current carried, since resistance heating is proportional to (current)2 . For a given power, current is inversely proportional to voltage. Thus raising the voltage from 69 to 390 kv would reduce the current by a factor 69/390 = 0.177 , for the same power transmission, and reduce the heating losses by 0.1772 = 0.031. So you can see why high voltage for long distance lines is essential. Obviously the limiting current on a power line has to be set by economic and practical considerations, but if this is predetermined and set, the limiting power will be that which produces that limiting current, and power = voltage x current. The actual limiting curent will depend on the line cross section, material, and length. The power that a line of a certain voltage can carry is calculated by using the following formula: (2.55×(KV)2 /1000) MW.
How come birds can land on power lines without being electrocuted?
The high voltage is between one wire and the other. From one point on the wire to another point on the same wire, the voltage is quite insignificant. As long as the birds don't touch both wires, nothing much will happen. The wire does not have a difference in voltage from foot to foot. The term "high voltage" refers from wire to ground. Electricity flows down a voltage gradient. There is no gradient of voltage between the feet.
Birds sitting on a single power line don't get shocked because there is no path for current to flow to the?
Ground
Where do power line birds nest?
Atop the power line poles.
Why don't birds get electrocuted when both of their feet are on a power line?
Because there is no ground. In order for them to be part of the circuit, there has to be a way for the electricity to more easily flow through them to something else then for it to continue travelling on the wire. because its not grounded
Birds sitting on a power line don't get shocked because there is no to ground.?
Birds are not good conductors of electricity. Their cells and tissues do not offer electrons an easier route than the copper wire they are already travelling along
Why is it that birds sitting on a single power line don't get shocked but if they placed one foot on each of two lines the current would flow between their feet and they would receive a terrible shock?
Yes, if one power line has a sufficient voltage difference to the first power line, the bird can be electrocuted. Normally, a bird has both foot one wire only, which cannot complete an electical circuit. In that case no electricity can flow through the bird. It often happens that a large bird such as an eagle or condor have wingspans of eight feet or more, and can touch two different power lines at the same time. Many birds have been found dead from this form of electrocution. For this reason, many newer power lines have greater spacing than the eight to ten foot wingspan of large birds.
How birds sitting on a single power line don't get shocked because there is no path for current to flow to the blank?
Birds are not good conductors of electricity. Their cells and tissues do not offer electrons an easier route than the copper wire they are already travelling along

Can you get electrocuted touching a power line with a wood?
Yes, you can get electrocuted if you touch a power line with wood, depending on the circumstances. Wood is an insulator, but if the voltage is high enough, it can become conductive, especially if it's wet or if there's enough current flowing. Additionally, if the wood creates a path for electricity to reach you, you can still be at risk of electrocution. Always maintain a safe distance from power lines to avoid danger.
How do birds not get electrocuted on power lines?
Actually if we were to sit on a power line and not touch anything else like the birds do we would not get electrocuted.The current a flow of electrons,flows along a path of least resistance the electrons want to get to where they are going in the easiest possible way. Electricity flows from one voltage to another value of voltage. For the birds, the power lines have the same voltage -- so the birds are safe. Don't approach power lines, because humans come from the ground, which is a sink for the current.
How do you spell electrocute?
The verb for to execute or kill by electric shock is indeed to electrocute.(Example : Touching a hanging power line can electrocutea person.)
