Question

Why is it possible for a bird to sit on a high-voltage wire without being electrocuted? Bird's webs (membrane uniting the lose) are very good insulators the internal resistance of a bird is infinite he potential drop across the bird is zero Birds are innocent creatures - what you do not know won't hurt you When a second bold is added in parallel to a circuit with a single bulb, the Brightness of the first bulb Increases Decreases Remains the same Can't tell A light bulb is connected in series with a capacitor to a voltage source in a circuit. the switch is initially open and the capacitor is initially uncharged. the bulb lights up when connected directly across the voltage source. What happens to the brightness of the light bulb after the switch is closed for a long time (when capacitor is fully charged)? the bulb is brighter the bulb is dimmer the bulb remains equally bright the bulb goes out Two parallel wires carrying current in the same direction will...each other Attract Repel None Can a constant magnetic field set into motion an electron at rest? Yes No A bar magnet has a north and south pole. How can you obtain one pole from the bar magnet? Break it into equal halves Break off a little piece from one end File one pole off' It cannot be done A compass needle placed near a current earning wire will deflect showing That an electric field exists around the wire That a magnetic field exists around the wire All of the above d. None of the above

Explanation / Answer

here,

To be electrocuted there has to be electrical current flow through the body. To get electrical current there has to be a complete path through which it can flow, like from the voltage source to ground. For a bird sitting on a high-voltage wire there is no path for current to flow to ground.

so, the electic potential drop across the birds feet is zero

the correct option is C
