What else can I help you with?
What happens if you shorten the resistance wire in a circuit?
It shortens
What happens to the resistance as the area increases?
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
What is a conductor made from?
depends on what you are conducting but generally a metal is a universal conductor. if it conducts electricity well then it will conduct heat well. some metals are better than others and you can figure this out by resistance values of the type of metal. more resistance makes it a less efficient conductor. insulators have very high resistance.
What happens to insulation resistance when decreasing cable length?
eat dick
When carrying out an insulation resistance test on a walloven with mineral insulated metal sheathed heating elements the minimum permitted insulation resistance is?
0.1M ohms
What happens to the resistance of a copper wire when it is heated?
The resistance of a copper wire increases when it is heated. This is because heating the wire causes the metal ions to vibrate more, increasing collisions with the electrons and hindering the flow of current, therefore increasing resistance.
What happens to the resistance of a common ohmic resistor when it is heated?
When a common ohmic resistor is heated, its resistance typically increases.
What happens to the electrical conductivity of a metal when it is heated?
it wil expand
What happens to pressure in a metal spray when heated up?
It heats up
Why is it difficult to state exactly what happens when a metal is heated?
i dnt know u tell me
What happens when heated metal is suddenly immersed in water?
The metal increases in hardness, a mechanical property. The process which transforms the metal hardness is called "quenching".
What happens to electrical resistance of most conductors when heated?
Resistance goes up creating more heat which eventually leads to an open circuit.
What happens to the resistance of metals as they get hot?
The electrical resistance in a common piece of metal such as copper wire would increase. This happens because as temperature increases the atoms of the metal vibrate quicker and to a larger extent resulting in a greater number of collisions for electrons moving along the metal.
What happens when a piece of metal is always heated?
It will bend eventually because u have heated it up so much it wouldn't be able to function It becomes molten like the lava in the earth.
What happens when metal plate with circular hole is heated?
When a metal plate with a circular hole is heated, the metal expands due to the increase in temperature. As a result, the size of the hole also expands slightly. This phenomenon is known as thermal expansion.
What happens to its resistance when an electrical device is heated?
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
