What is an electrical conductor that has very low resistance to current at low temperatures called?
You're thinking of a "superconductor", but the real definition is far more bold.
A superconductor isn't a substance that has "very low" resistance at low temperatures.
It's one that has NO resistance at very low temperatures. None whatsoever. I mean, literally,
you can make a coil of wire out of this stuff, keep it super-cold, pump an electric current into the
wire, and connect the ends together, and the current is still flowing around the coil months later !
I know it sounds incredible, but that's exactly what they do every day, in CT and MRI machines.
What else can I help you with?
When current passes through a conductor what makes the conductor heat up?
When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
What slows an electrical current?
Factors that can slow down an electrical current include resistance in the conductor, length of the conductor, and presence of any insulating materials. Resistance converts electrical energy into heat, reducing the current flow. Longer conductors offer more resistance to the flow of electrons, which slows down the current. Insulating materials can also impede the flow of electrons in a circuit.
What is encountered by the electric current while flowing through a conductor?
The electric current encounters resistance while flowing through a conductor, which results in the conversion of electrical energy into heat. This resistance is impacted by factors like the material of the conductor and its dimensions.
What element is a good conductor of electric current?
Copper is a good conductor of electric current due to its high electrical conductivity. It is commonly used in electrical wiring and circuitry because it allows electricity to flow with low resistance.
Is nylon an insulator or conductor?
Nylon is an insulator because it does not conduct electricity. It has high electrical resistance, which prevents the flow of electrical current through it.

What are the three electrical guantities?
The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
Can an overhead conductor carry more current on a cold day as compared to a hot day?
The only limit on how much current the conductor can carry, regardless ofthe weather, is the amount of current that causes the conductor to melt.The current in such a conductor depends on the voltage between its ends,and on the resistance of the conductor. The resistance of the conductor issomewhat less when it's cold, so a given voltage would result in more current.

What is the path that an electrical current travels?
electric current

What may cause an electrical conductor to heat up?
An electrical conductor may heat up due to excessive current passing through it, which increases its resistance and generates heat. Poor connections, overloading, or inadequate conductor size can also cause heating. This can lead to a potential fire hazard if not addressed.
What element is a good conductor of electric current?
Copper is a good conductor of electric current due to its high electrical conductivity. It is commonly used in electrical wiring and circuitry because it allows electricity to flow with low resistance.
The current in an electrical conductor varies inversely as the resistance of the conductor The current is 2 amperes when the resistance is 960 ohms What is the current when the resistance is?
When the resistance is 960 ohms and the current is 2 amperes, we can use the formula for inverse variation: ( current \times resistance = constant ). Thus, ( 2 \times 960 = constant ), which is ( 1920 ). So, if the resistance changes to a new value, we can find the new current by dividing the constant by the new resistance.
Is nylon an insulator or conductor?
Nylon is an insulator because it does not conduct electricity. It has high electrical resistance, which prevents the flow of electrical current through it.
What is the opposition to the flow of electrons is called?
Resistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistance
What is the resistance value?
Electrical resistance is measure in Ohms. A function of voltage divided by current. It is also dependant on the length and cross sectional area of the conductor.
