Electric resistance is greater in a long thin wire compared to a short fat wire, due to the higher resistance associated with longer wires and thinner cross-sectional areas. Resistance is determined by the material's properties and dimensions, with length and cross-sectional area being key factors affecting resistance.
What else can I help you with?
Is electric greater in a shorter fat wire or a long thin wire?
Electric resistance is greater in a longer, thinner wire compared to a shorter, fatter wire due to increased collisions between electrons and atoms in the longer wire, leading to higher resistance. This is described by the formula R = ρL/A, where R is resistance, ρ is resistivity of the material, L is length, and A is cross-sectional area.
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
Does a short copper wire have more resistance then a long one?
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
Does a long wire have more resistance than a short wire?
Yes, a long wire typically has more resistance than a short wire due to increased electron collision and higher impedance over a longer distance. This is because resistance is directly proportional to the length of the wire.
What has a lower resistance a long thin iron wire at high temp or a short thick copper wire at low temp?
A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.
Is electric resistance greater in a short wire or a long thin wire?
Resistance is the restriction of electrical flow in a component/wire/etc. If you think of a short fat wire as a short freeway and a long thin wire as a quiet country road then the answer is easy to find especially if you imagine 1 thousand cars all trying to travel the distance at once
How long can an electric circuit be?
The length of an electric circuit can vary depending on factors such as voltage, current, and wire gauge. In general, the longer the circuit, the higher the resistance and the greater the loss of electrical energy. It is recommended to keep electric circuits as short as possible to minimize energy loss and ensure efficient operation.

Electric resistance is greater in a longer, thinner wire compared to a shorter, fatter wire due to increased collisions between electrons and atoms in the longer wire, leading to higher resistance. This is described by the formula R = ρL/A, where R is resistance, ρ is resistivity of the material, L is length, and A is cross-sectional area.
Which has a greater mechanical advantage along or short wide wedge?
a long wedge has a greater mechanical energy then a short wide wedge.
Does long wire have a lower or higher resistance than short wire?
A long piece of wire will have more resistance in it than a shorter one of the same material.
How does the resistance differ between long and short wires?
Generally, the longer the wire, the more electricity will be lost because of resistance.
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
Electric current flows in a wire which is opposed by what?
Electric current flowing in a wire is opposed by electrical resistance. This resistance is caused by factors such as the material of the wire, its length, and its cross-sectional area. It results in the conversion of electrical energy into heat.
Does a short copper wire have more resistance then a long one?
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
Why don't AC input wires to a transformer just short circuit?
The resistance of the winding in the primary of a transformer constitutes a load. As long as there is resistance then there is no short circuit. A short circuit is considered no resistance which develops an instantaneous high current. That is why fuses and breakers are inserted into the circuit to open the high current flow under a short circuit condition.
Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.
Which has a greater mechianical advantage short ramp and a long ramp both reach a height of 1m?
The long ramp.
