we know current always flow from a body at high potential to a body to a low potential ,then why does AC current changes its direction?

Solution

Alternating current is created by an AC electric generator which determines the frequency.In the case of AC, voltage can be readily changed.In AC generator a slightly different configuration alternates the push and pull of each generator terminal. Therefore the current in the wire moves in one direction for a short while and then reverses its direction when the generator armature is in a different position.

Q. State whether given statement is True or False
Conventional current always flows from a body having high electron density to body having low electron density.

A conductor $A B$ is joined to a cell with its end $A$ at a low potential and the end $B$ at a high potential. The direction of flow of current in the conductor is from $A$ to $B .$

Two electrodes A and B are coupled. A has standard electrode potential 0.24V and B has 0.55 V. In which direction flow of current will be observed and why?

Q. 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 ?
