Which wire has higher resistance nichrome or copper?

Obviously Nichrome because resistivity of Nichrome is greater than that of Copper. As mention above, both wires are of same length and having same cross section area. Therefore resistance of Nichrome wire will be more than that of Copper. Since more resistance means more I^2R loss (which is dissipated as heat).

What is the reason for getting more heat in copper wire?

Due to the wires having electrical resistance, which means that they resist the motion of electrons, the electrons bump into atoms on the outside of the wire, and some of their kinetic energy is given to the atoms as thermal energy. This thermal energy causes the wire to heat up.

Which is better nichrome or copper?

Nichrome being 100 times more resisistive than copper produces good amount of heat when current passed through it and it overcomes the usage of copper having low resistivity and high conductivity in heating coil.

Does copper wire heat up?

Good Thermal Conductivity. Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.

Why does a nichrome wire gets heated in an electric circuit?

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 wire has more resistance than copper wire?

Iron wire
Iron wire has more resistance than copper wire.

What happens when copper gets hot?

Copper oxidizes to copper When copper is heated in air, it is oxidised to copper (II) oxide and the reddish brown metal turns black as the copper is oxidised to copper (II) ions. Hence the copper is changed to copper oxide. Therefore, the copper gains oxygen in accordance with the given reaction.

What causes heat in wires?

The electrical current through the wires itself causes the home wiring to heat up. This is because as the electrons flow they come across the resistive forces of the medium’s material, releasing energy that is expended in the form of heat energy.

Why nichrome wire heats up more as compared to the copper wire?

Nichrome wire gets heated up more. So more the resistance of a wire, more will be heat generated in it. Hence, we can say nichrome wire gets more heated up as compared to the copper wire.

What causes heated wires?

Why does a copper wire not get heated in an electric circuit whereas Nichrome does?

This is because copper wire offers no resistance and thus electric current passes through them without producing heat energy whereas in nichrome offers a large resistance and thus the mechanical energy of the drifting electrons changes to heat energy rapidly .

Why is the resistance of nichrome wire greater than that of copper?

Resistance of nichrome is greater than copper wire of same length and same radius, because the former has greater resistivity. In series, Power loss P= I 2R. Because of higher resistance power loss and heating up of nichrome wire is more than that of copper.

Why does a thin wire heat up faster than a thick wire?

If the wires are made of the same material and the same amount of current is applied to each wire then the thin wire will heat up more. R = resistance of thick wire. I = current applied to the wire. From above with the same amount of current the thin wire generates twice the heat.

Why do some transformers have thicker wires?

Thicker wires conduct larger currents at given voltage difference, which is to say they have higher conductance (lower resistance). Dwayne is in hot water for his latest comments. The big companies don’t want you to know his secrets. Why do some transformers have 3 wires and the other side has two wires?

What happens to atoms when a conductor is heated?

When a metallic conductor is heated, the atoms in the metal vibrate with greater amplitude and frequency. Due to increase in temperature, the thermal velocities of free electrons also increases. Therefore, the number of collisions between free electrons and atoms increases.
