an electrician working with electric connections often hold one of the two electric wires connected to an electric socket having electric current in it . He is not harmed in anyway .Give reason

they are coated with plastic coating to prevent him from getting shock or harm.
plz mark me as brainliest
He touch the neutral wire not the live wire.
The live wire is at a high potential (its magnitude and direction keeps changing at a specific frequency), but it is not at zero potential.
On the other hand the neutral wire is at zero potential and always remains at that potential.
Also remember that your feet are touching the ground(earth) which is also at zero potential.
Now when you touch the live wire one end of your body is at a non zero potential while the other end is at zero potential this causes electrical current to flow through your body giving you a shock whereas when you touch a neutral wire almost no current flows through your body hence you do not get a shock.
