Why don Birds on a wire get a shock?
The fact is, for a living creature to get a ‘shock’ there has to be a substantial flow of current through the body. However, there is barely any current running through the bird’s body for two reasons. Firstly, the bird not only forms a circuit with the wire, but it also offers a high resistance to current, so the current passes through the wire instead of the bird. It’s a bit like this, would you prefer going on a smooth road or a road full of potholes? The answer is obvious and just like you, the current prefers taking the easier path. All objects offer some amount of resistance to the flow of current, depending on the material. This is just one of the reasons why birds don’t get shock, however the more important reason why current does not pass through the bird is, there is barely any, if at all, voltage difference across the bird. Current flow is actually just the flow of minute charged particles that are invisible to the naked eye. These charged particles need an energy input in o
