Can a short circuit occur when a neutral wire is earthed, example a man touches a bare neural wire with bare hands..? And is the effect different for alternating and direct current?
Godwin Kessy said:I never thought i could not have any idea on this... What i know when the circuit is completed.. meaning the live connected to neutral.. Current flows whether it's dc or ac.. and earthing a device as i knew is only due to grounding the static charges that might result in the metallic parts of the device.. A challenge came up when a friend of mine just said that the body of the car works as neutral... Okay it's possible since it's a conductor but... is it not going to be harmful? There is where the question arose...

If it becomes part of your circuit, current can flow through it.
Sparky's automobile is separated from Earth by the rubber tires which are very good insulators. So the only current likely to flow between a car battery and Earth is that "static" charge you feel on cold dry winter days when exiting the vehicle.

A short circuit is a situation where there is an unintentional connection between two points in an electrical circuit that have a low resistance, causing a large flow of current and potentially damaging the circuit.
No, the Earth cannot experience a short circuit in the traditional sense because it is not an electrical circuit. However, it is possible for certain parts of the Earth's surface, such as power grids, to experience power surges or failures which can mimic the effects of a short circuit.
A short circuit can be caused by a variety of factors including damaged wires, faulty insulation, and human error. It can also be caused by natural events such as lightning strikes or power surges.
A short circuit can be dangerous as it can cause overheating, fires, and explosions. It can also damage electrical equipment and lead to power outages.
There are several ways to prevent short circuits, including proper installation and maintenance of electrical systems, using circuit breakers and fuses, and avoiding overloading circuits. It is important to follow safety guidelines and consult a professional if you suspect a short circuit in your electrical system.
