Which wire is the best conductor of electricity between copper and Nichrome?

Which wire is the best conductor of electricity between copper and Nichrome?

The substance which has high resistivity and low conductivity value would get heated up fast and more. The metal satisfying this criteria in the question is Nichrome. Where as Copper has high conductivity and low resistivity making it a better conductor of electricity than Nichrome.

Which wire is thicker copper or Nichrome?

Answer: Nichrome has more resistivity than copper. Hence for equal length and resistance it has to to be thicker since resistance is inversely proportional to the diameter of the wire.

Why Nichrome wire has more resistance than copper wire?

melting point for a nichrome wire is greater than copper wire, so that the resistance at nichrome wire will be greater than copper wire.

Why does nichrome wire heat up first?

Nichrome and copper wires of same length and area of cross-section are connected in sereis, current is passed through them. Why does the nichrome wire get heated first? Since resistivity of nichrome is greater than that of copper, hence heat produced in nichrome wire will be more than that of copper wire.

Is nichrome wire a good conductor of electricity?

Nichrome is a good conductor, being a metal having resistivity much higher than all insulators. However, its resistivity is much higher than copper or aluminium, which makes resistance from this metal large enough to get a workable value in very small dimensions. Hence it is used as a resistance material.

Why does nichrome wire get heated?

Nichrome due to its high resistivity does not allow the electric energy easily to pass through it. This electrical energy is changed into heat energy. So nichrome wire gets heated in an electric circuit.

Which is more thicker copper or manganin?

Two wires of equal length one of copper and other of manganin have the same resistance. Since ρ is grater for manganin than for copper, hence manganin wire is thicker than copper wire.

Which wire gets heated up more of nichrome and copper?

Since resistivity of nichrome is greater than that of copper, hence heat produced in nichrome wire will be more than that of copper wire.

What is nichrome wire calculator?

Nichrome is wound in coils to a certain electrical resistance, and current is passed through it to produce heat. Use this online nichrome wire calculator to calculate resistance, power, current and voltage of the Nichrome coil by just providing the length, thickness and temperature of the NiCr. Nichrome is an alloy of Nickel and Chromium.

What does the V-I graph of the nichrome wire shows?

The V-I graph of the nichrome wire shows a straight line. It means that the resistance of the wire remains constant when the current supply is changed. It follows the ohm’s low and therefore, it is considered as ohmic conductor.

How does voltage affect the conductivity of a nichrome wire?

The voltage is the “push” on the electrons, and their flow is the current. If you have a nichrome wire and a copper wire the same size and shape, with the same voltage on them, much more current will flow through the copper. We say that the copper has higher ‘conductivity’

What is nich nichrome coils?

Nichrome is an alloy of Nickel and Chromium. It has high corrosion resistant and melting point hence it is used in electric appliances and tools. Type A and Type C are the common types of NiCr coils.
