The resistance of a wire is determined by the following formula. R = (rho)L/A, where the greek letter rho (it looks like a p) is a value assigned to a material based on how resistive it is by nature, L is the length of the wire, and A is the cross-sectional area (AKA how thick the wire is). Increase the length, or change the material to something with higher restistivity. Hope this helps!

What are two ways to alter the wire to increase the resistance in the electric circuit?

The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.


What are two ways to increase the current in a wire?

Increase the voltage applied to the wire. Decrease the resistance of the wire.


Does a longer wire equal resistance?

Wire is not equal to resistance. If you have two pieces of wire with the same thickness, composition, and temperature, the longer piece has higher electrical resistance.

What are two ways you could alter the wire to increase the resistance in the electric curcuit?

You could increase the length of the wire or decrease its thickness to increase resistance in the electric circuit. Both of these changes will hinder the flow of electrons through the wire, resulting in higher resistance.


What is the effect on its resistance if a resistive wire is elongated?

If a resistive wire is elongated, its resistance will increase. This is because the longer length of wire will result in more collisions between electrons and the wire's atoms, leading to higher resistance. The resistance of a wire is directly proportional to its length.


If two wires of the same material have the same thickness but different length the blank wire will have greater resistance?

The thinner the wire, the higher the resistance. The thicker the wire, the resistance decreases. Think of it this way. The thick wire has more room for electrons to jump around, but the thin wire has less room.


What are the two ways to increase the resistance of a wire?

You don't specify what you are referring to. However, if your question relates to resistance in general, then you should know that resistance is directly-proportional to the length of a conductor and to its resistivity, and inversely-proportional to its cross-sectional area. Resistivity is a characteristic of the material from which a conductor is made, and varies from one material to another.This means that you can increase resistance by increasing the length of a conductor, or by decreasing its cross-sectional area, or by selecting a conductor manufactured from a material with a greater resistivity (e.g. by using aluminium rather than, say, copper).


What are two ways increase the current in the wire?

You can increase the current in a wire by increasing the voltage applied across it or by decreasing its resistance. Additionally, increasing the cross-sectional area of the wire can also help facilitate higher current flow.


If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?

The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).


What are the two factors of a wire that will alter its resistance?

The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.


Why bends in a wire do no affect its resistance?

Bends in a wire do not affect its resistance because the cross-sectional area and length of the wire remain the same regardless of the bends. Resistance is determined by these two factors, according to the formula R = ρ*(L/A), where ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area. As long as these parameters remain constant, the resistance of the wire will stay the same.
