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.
What else can I help you with?
How does short circuit occur?
A short circuit occurs when a low-resistance path is created between two points in a circuit, causing excessive current flow. This can happen due to a wire touching another wire, a conductor coming into contact with metal objects, or a component failure. When a short circuit occurs, it can potentially lead to overheating, damage to components, and even fire.
What wire in a circuit should contain the fuse?
The wire that connects the power source to the rest of the circuit should contain the fuse. This is typically the wire that leads directly from the positive terminal of the battery or power source. Placing the fuse in this wire helps protect the circuit in case of a short circuit or overload.
Do you connect a fuse to the live wire or the neutral wire?
A fuse is typically connected to the live wire in a circuit. This is done to protect the circuit from an overload or short circuit, as the fuse will blow or trip and cut off the current flow if there is an issue.
Why are the live wire and neutral wire never joined together?
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.
An open circuit results when a hot wire touches ground?
An open circuit occurs when there is a break in the electrical path, cutting off the flow of current. When a hot wire touches ground, it can create a short circuit where current flows directly to ground instead of through the intended circuit, leading to potential danger and damage to the equipment.
Why wiring short circuit?
A "hot" positive wire has made contact with ground = short circuit.
Why would a computer wire melt?
Short in the circuit or the circuit was overloaded.
What happens if a wire breaks?
The circuit stops working because of the short circuit

Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"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.
How do you correct a short circuit?
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.

Why is the three-layer insulated coil less prone to short-circuit failure?
Coiled around copper core wire, no flow blocking element. Why is this insulated wire coil not prone to short-circuit failure?
Why a coiled wire does not short the circuit?
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.
What is principle of Current transformer?
why does have to short-circuit secondary wire of current transformer ?
What blows ignition fuse?
A blowing fuse is an indication that there is a short circuit condition in that circuit. A short circuit condition is the result of a "hot" wire or component in a circuit coming into contact with another wire or component which is "grounded." Grounded means that a metallic component is somewhere connected to the ground post [terminal] on the battery.
