For an electric current to pass through the bird's body, there must be a potential difference (voltage) across its legs. But its legs are connected to a very good conductor which means that the bird's legs must be at the same potential -no potential difference, no shock!

What is meant by over head lines?
The electric wires which come to your house through the tall poles which stand on road side. These wires are called overheadcables
Can you get electrocuted on an electrical wire if you're not touching th?
['No' is the correct answer to this question. But it's a technical answer. There are a lot of if's, and's or but's involved. How, for instance, how do you touch one wire without touching anything else? On what are you standing? On what are you suspended? See how this works? If one was foolish enough to climb a telephone pole that had high voltage wires atop it and reached out and touched the wire, a fatal shock would almost certainly result. But if one somehow got atop the pole and jumped off and grabbed hold of the wire, no electric shock would occur. Birds sitting on wires don't get electrocuted. Remember that 'No' is the technically correct answer, but there are a lot of "loose ends" that must be thought through when considering this question. There are safety considerations to be assessed, and fatal consequences await the careless individual.] Yes. Most wires have a two or three pathways (conductors) wrapped together. One of these is usually the ground wire. If you come into contact with the ground and the hot wire, you can be shocked. Another way to look at this question is to think of "ground" as standing on the ground. If a person touches a live wire with a single contact point, but their body is not touching the ground or a grounded surface or a grounded object, then that person will not be electrocuted. That's because a complete circuit can not be made until you are grounded, or until you touch another circuit wire at the same time. You will not know for sure unless you have a test instrument. A wise person would not guess. For example, think of when a bird sits on a live high voltage wire between poles. The bird does not get electrocuted because the bird is not grounded. That bird is not completing a circuit path and cannot be shocked. However, if the voltage is high enough, the voltage can go right through the air (think lightning). A link is provided to the Wikipedia article on electric shock. It's worth a skim.
Is a feather synthetic?
No. They come from birds.
When did Michael Faraday come up with the electric motor?
The Electric motor was invented in 1821 by Michael Faraday.
When live neutral wires in a domestic circui t come in contact with each other what occurs?
If the live and neutral wires come into contact the circuit is completed and a current will flow. Since there is no appliance in the circuit and the resistance in the wires is low the current will rapidly rise to high levels. Typically a safety device, a fuse or circuit breaker, will then react and stop the current flowing. The reaction speed of the safety devices is normally not quick enough to prevent a shower of sparks (molten metal) and melt damage to the wires where they touched.
Can birds get electrocuted if they come in contact with two wires?
Yes, a bird can get electrocuted if it comes in contact with two bare power lines. The power lines are spaced apart so only the largest birds (buzzards, eagles, etc.) would be able to touch two at the same time.
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.
Why is it essential to earth electrical appliances having metallic body?
if the appliance shorts out (if one or more of the wires inside it come into contact with the outer casing) the electricity will take the shortest route to be neutralised. If there is no earth wire and you touch the shorted out appliance then the shortest route to neutralise the electric charge is through you, and you will be electrocuted. If an earth wire is present then the shortest route to neutralise the current will be through this wire, so you would not be electrocuted if you touched the shorted out appliance.

How come birds on electric wires dont get electroucuted?
They are not grounded. Electricity is going to take the shortest route possible and with the least resistance...therefore it is "easier" for the electricity to travel in a straight line through the metal cables than to travel up and back down again through a bird which is not conductive. If you were to hang from a power line (assuming you didnt come close to another one) you would not be electricuted, only if you touch the ground or another wire or pole will you get zapped.Answer The resistance of the wire between the bird's feet is so low that the current passing through the conductor cannot create sufficient voltage drop to harm the bird. Should part of the bird come into contact with another line conductor, or an earthed conductor, then it will be killed.
Why do birds not electrocuted when they are staying on live wire or wires?
Power lines are insulated and as long as they don't touch the ground (or another object) they won't be electrocuted.AnswerMost power lines are not, in fact, insulated because they are already surrounded by an insulating media -air.The reason that birds don't get electrocuted is because each foot is at the same potential and, for current to flow (it's the current which causes electrocution) through its body, each foot must be at a different potential. The bird is safe, providing another part of its body doesn't come in contact with one of the other conductors.
Why do the interior lights on your 93 olds 98 not come on when the doors are opened and also the electric locks don't operate properly?
fuse or broken ground in wires
What happens to an electric motor if it is over heated?
If a fuse fails to blow or a cut-off doesn't come into play, the insulation on the wires will melt and cause a short circuit.

They come the same way all other birds come from. An egg.
