How does the length of a Nichrome wire affect its resistance?

How does the length of a Nichrome wire affect its resistance?

As the length or the wire increases, the current decreases. As the length of wire increases, the voltage increases but after 25cm, the voltage stays at 2v. As the length of wire increases, the resistance increases.

What should be the length of Nichrome wire of resistance?

So, required length will be 108cm.

How does the length of a wire affect resistance?

First, the total length of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be. In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.

What will be the length of a Nichrome wire?

Since resistance R=rho×l/A where l is the length of the wire. l2=240 cm.

How the resistance of the wire varies with the length and diameter of the wire?

A longer wire also means that it would have more atoms, which means it will be more likely for moving electrons to collide with them; hence, higher resistance. Therefore, the longer the wire, the higher the resistance.

What is the resistance of a wire?

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 will be the resistance of a metal wire of length 2m and 0.6 mm in diameter?

Resistivity of the wire is 7.065 × 10^-8 Ω m. Hope it helps…!!!

What will be the length of a Nichrome wire of resistance 5.0 ohm if the length of similar wire of 120 cm has resistance of 2.5 Ohm Why?

How do you calculate wire length?

To calculate spring wire length per coil, you must subtract the wire diameter from the outer diameter in order to get mean diameter. Once you have calculated mean diameter, multiply it by pi (3.14); this will give you the length of wire per coil.

What is the length of Nichrome wire of resistance 5 ohm?

So, required length will be 160cm.
