What cause battery positive terminal to melt?
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.
Which material has a greater resistance aluminum or copper wire?
Aluminium wire has high resistance than Copper.
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.
Does thickness of wire affect resistance?
yes.it affect.because thick wire cannot hold high resistance of current
Is fuse wire characterized by high resistance and high melting point?
Fuse wire is charaterized by high resistance and low melting point to avoid surge of ac current through it.
Does thin wires have high or low resistance?
Other things being equal, a thin wire will have a higher resistance than a thick wire.
Which is a better conductor between a short wire and long wire?
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.
What happens to resistance of the wire if the wire is short?
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?
No, a smaller diameter wire has a higher resistance. The 0.01 mm wire will have 1/100 the cross-sectional area of the 0.1 mm diameter wire, therefore the resistance will be 100 times as high.
enameled aluminum?
Enameled aluminum wire has excellent high temperature resistance
What are the properties of a fuse wire?
It has high specific resistance and low melting point.........
Why does nichrome get hot?
Nichrome has a high electrical resistivity.
