Frequent question: Which has less electrical resistance among the wire of the same material?

Thick wire has less electrical resistance.

Which has less electrical resistance wire or?

A thick wire has a greater area of cross-section, whereas a thin wire has a smaller area of cross-section. Also, the resistance of a conductor is inversely proportional to its area of cross-section. This means that a thick wire has lesser resistance than a thin wire.

Which has less electrical resistance a thin wire of the same length and same material?

Resistance increases with small area of cross section and decrease with large area of cross section. thin wire has small area of cross section while thick wire has large area of cross section. Thus thick wire will have less electrical resistance.

Which has more resistance a thick or thin wire of the same material?

Resistivity depends on the nature of the substance and temperature. It does not depend on the dimensions, so resistivity of both is same. However the resistance of the thin wire will be more than that of the thick wire.

Which wire has the most resistance?

Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures. When used as a heating element, it is usually wound into coils.

Which wire has less resistance a long wire or a short wire?

The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. The relationship between resistance and wire length is proportional .

Why is there less resistance in a thicker wire?

The larger the cross sectional area, the lower the resistance since the electrons have a larger area to flow through. This will continue to apply no matter how thick the wire is. The electron flow will adjust itself to whatever the wire thickness is.

What does the resistance of a wire depend on?

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. See resistivity. The resistance of a conductor, or circuit element, generally increases with increasing temperature.

What is thickness of thin wire?

Answer: Measure the length of the coil with the help of a meter scale. The thickness of wire can be found by dividing the length of the coil by the number of turns.

Does resistivity depend on the length of a conductor?

Resistivity is material property. It depends only on the material of the conductor. It does not depend on the shape and size of the conductor.

Which has more resistivity a thick or thin wire of same material when connected to the same source and why?

It is because the resistance of a conductor is inversely proportional to its area of cross-section. If the thicker the wire, the less is resistance and hence more easily the current flows.

Which of the following metal has the least electrical resistivity?

The correct answer is (B) Silver. Silver has the lowest resistivity with the highest thermal conductivity. The resistivity of silver is about 1.59 * 108Ω m at 20° C, which is the lowest among all other metals. Explore more such questions and answers at BYJU’S.

Which offers more resistance a thick wire or a thinner wire what happens to the resistance as the conductor is made thinner?

The resistance of the wire will increase if we made the conductor thinner because R (resistance) = p (rho). l (length) / A (area of cross-section or thickness of wire).
