A bird sitting on a single high tension wire does not get electrocuted because

A bird sitting on an insulated wire carrying a current feels quite safe because.

A bird flying high up in air does not cast shadow in the ground because

Honey that a high concentration of sugars, does not decay because

A high tension wire is at a high potential with respect to a wire which is well grounded called Earth wire. You must have seen such wires stretched parallel to roads. There is a high tension wire between two points A and B. 1 km apart. The distance between HT wire and earth wire is 1 m. The resisatnce of the HT (and also the earth wire) is 1 Omega//m . This wire is at a potential of 11 KV at point A w.r.t. to earth wire. and its is carrying 1 A current which returns back to the generator by through the earth wire. This wire is quite a thick wire. There is a sign board at a pole over which this wire is stretched reading DANGER, 11 KV. You might thick what would happen if one touched this wire. Will one feel a shock or not. Well ! it depends on whether the current through our body exceeds a particular valuem which we may call CRITICAL CURRENT. Consider a bird having effective resistance 10 Omega between its feet sitting on this high tension wire. The distance between its feet is 10 cm. Find the potential difference between the feet of the bird is approximately,
