Usually low resistance is better.
There are two related causes for any connection to melt. The resistance of the connection was high causing excess heat OR The Power draw was to high for the connection. In your case either the connection was dirty or there was short further down the wire.
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
"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.
High resistance in a copper wire can be caused by factors like a longer wire length, a thinner wire diameter, and the material's high temperature, which increases resistance due to increased collisions among electrons.
Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.
No, the wire with a diameter of 0.01 mm will have higher resistance compared to a wire with a diameter of 0.1 mm. Resistance of a wire is inversely proportional to its cross-sectional area, so a thinner wire will have higher resistance.
A thin and long wire made of a material with high resistivity, such as nichrome or tungsten, would have the greatest electrical resistance.
To test a wire with a multimeter, set the multimeter to the resistance or continuity setting. Touch one probe to each end of the wire. If the multimeter shows a low resistance or beeps, the wire is continuous and working. If there is high resistance or no beep, the wire may be broken or faulty.
No, fuse wire is characterized by low resistance and a low melting point. This allows the fuse wire to melt quickly and break the circuit when there is an overload of current, thereby protecting the circuit from damage.
To test a wire with a multimeter, set the multimeter to the resistance or continuity setting. Touch one probe to each end of the wire. If the multimeter shows a low resistance or beeps, the wire is continuous and functioning properly. If there is high resistance or no beep, the wire may be broken or faulty.
A long and thin wire made of a material with high resistivity and low conductivity would have the greatest electrical resistance. The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area, so a long, thin wire will have a greater resistance compared to a shorter, thicker wire.
To test thermostat wires, use a multimeter set to measure resistance. Disconnect the wires from the thermostat and touch the multimeter probes to the wire ends. A reading of zero or close to zero indicates a good connection, while a high resistance reading suggests a faulty wire.
