This will depend on the circuit configuration, and the wire.
For two equivalent types of wire (same covering, thickness, cross section, but different lengths) in a series circuit, where the surrounding on both wires is kept equivalent, heating will be equal per unit length (meaning the wires will reach the same temperature); The longer wire will use more power, which will cause more room heating (due to the longer length), but the wires themselves will reach the same temperature.
For the same two wires in a parallel circuit, the smaller wire will heat up more due to a larger current flow through it, thus a higher I^2 * R loss (heat loss) per unit length.
If two wires are put in parallel, and have different lengths, but are made to have the same resistance, the exact same amount of current will flow in each, but the shorter one will inherently have a higher resistance per unit length, causing it to become hotter than the longer wire.
short circuit occurs when two wire which consist of one live and neutral wire are in contact with the main and the other end of the wire are touched each other short circuit occurs
Yes, the ground wire should all ways be connected. This is the short circuit current return path that trips the breaker in case of a short circuit in the unit.
the red wire and the blue wire A touching of two wires coming from any potential power source will cause a short circuit Short circuit relates to the quickest path back to the source with out any resistance to the current flow.
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
A short circuit is the term for hot touching ground. This can cause a breaker to trip which will then open the circuit.

A "hot" positive wire has made contact with ground = short circuit.
Short in the circuit or the circuit was overloaded.
The circuit stops working because of the short circuit
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.
A short circuit is repaired by first finding out where the short circuit occurred. On major faults usually the wires are removed and new wires are installed. On minor faults, the wire that shorted is separated from the offending wire or separated from the grounding medium. To put the conductor back into service the wire's insulation has to be brought back to the level of what the wire was when it was new. Once that is done the circuit can be re-energized.

Coiled around copper core wire, no flow blocking element. Why is this insulated wire coil not prone to short-circuit failure?
I suspect that it is because a coiled wire becomes an electro-magnet which disipates and uses energy, and is therefore not recognized as a short.
Presumably, the current follows a path (a circuit) to do whatever it was "made" to do. If water, for instance, enters the circuit, a shorter path may develop, and the current will (partially) take the short circuit. Or a wire could become lose and short circuit the intended path.
why does have to short-circuit secondary wire of current transformer ?
