If two points are at different potentials , then the current will flow till the time both the points reach the same potential( without a battery). Now the question is that - If we connect the switch in the neutral wire, when the switch is off, the appliance is connected to the higher potential through the live wire ( which was not disconnected), the current flows through the live wire to the appliance . If we now touch the appliance, we will get shock because the appliance was at higher potential and our body was at a lower potential, thus current moved Through our body. But even if we wear rubber shoes ( or some insulation between our body and earth is there) , we should get shock because the only change that happens now is that the current doesn't reach ground. But it will flow TO our body (lower potential ) from the live wire (higher potential) even if there is not a return path for current ( not a complete circuit). Why is this not true ? |
