The earth wire is made longer and thicker to ensure that it can safely conduct excess current or fault current to the ground in the event of a short circuit or electrical fault. The longer and thicker wire reduces the resistance, allowing for a more efficient path for the current to flow, thus ensuring effective earthing and protecting against electric shock.

When a wire is made thicker it resistance?

When a wire is made thicker it's resistance decreases.


When a wire is made thicker it's resistance is what?

When a wire is made thicker, its resistance decreases. This is because a thicker wire offers more pathways for the flow of electrons, reducing the likelihood of collisions and increasing conductivity.


When wire is thicker its resistance is?

When a wire is made thicker it's resistance decreases.


Describe how the electric resistance of a wire changes as the wire becomes longer. How does the resistance change as the wire becomes thicker?

As the wire becomes longer, its resistance increases because there is more material for the electrons to travel through. On the other hand, as the wire becomes thicker, its resistance decreases because there is more space for the electrons to flow, reducing the collisions with the wire material and therefore lowering the resistance.


Would a long and thick wire have the greatest resistance?

No, resistance is primarily determined by the material the wire is made of, its length, and its cross-sectional area. A longer and thicker wire would actually have lower resistance due to more space for electrons to flow through.


What type of wire will have the most resistance?

A longer and thinner wire will have more resistance compared to a shorter and thicker wire. This is because the longer wire results in greater opposition to the flow of electrical current, while the thinner wire offers less space for electrons to flow through, thus increasing resistance.


What does the resistance of the wire depend on?

The resistance of a wire depends on three main factors: its length, its cross-sectional area, and the material it is made of. Generally, longer wires have higher resistance while thicker wires have lower resistance. The material's resistivity also plays a significant role in determining the wire's resistance.


What property of wire increases when it is made longer?

Its length, obviously. But also its electric resistance.


What three things affect the resistance in a wire?

The three main factors that affect the resistance in a wire are the material of the wire (different materials have different resistivities), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance).


Is 8 gauge weld wire fencing stronger than 10 gauge wire?

Yes, 8 gauge wire is thicker and stronger than 10 gauge wire. The lower the gauge number, the thicker the wire is. Therefore, 8 gauge weld wire fencing would be stronger and more durable than 10 gauge wire fencing.


How does the thickness of wire affect the resistance?

Thicker wire has less resistance than thinner wire due to lower electrical resistance. Thicker wire allows more electrons to flow through it easily, resulting in less opposition to the flow of electric current.


What is thicker 8 gauge or 10 gauge?

8 gauge wire is thicker than 10 gauge wire. In the American wire gauge (AWG) system, lower gauge numbers indicate thicker wire. Therefore, 8 gauge wire has a larger diameter and can carry more current than 10 gauge wire.
