Do bends in a wire effect its electrical resistance?
Yes, bends in a wire can increase its electrical resistance due to the deformation of the metal lattice structure, which interrupts the flow of electrons. This increased resistance can lead to energy losses in the form of heat.
Why does heating a metal wire affect its electrical resistance?
Heating a metal wire affects its electrical resistance because as the wire heats up, the atoms within the wire vibrate more vigorously, causing more collisions with the electrons flowing through the wire. This increased collision rate hinders the flow of electrons, leading to a higher resistance in the wire.
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.
How does the size of the wire affect the electrical resistance?
The size of the wire directly affects the electrical resistance. Thicker wires have lower resistance compared to thinner wires, as there is more space for electrons to flow through, reducing the resistance. Conversely, thinner wires have higher resistance due to smaller pathways for electron movement.
What kind of wire would have the greatest electrical resistance?
A thin and long wire made of a material with high resistivity, such as nichrome or tungsten, would have the greatest electrical resistance.

How do you ohm out a wire to test its electrical resistance?
To ohm out a wire and test its electrical resistance, you need a multimeter. Set the multimeter to the resistance (ohms) setting. Connect the multimeter's probes to each end of the wire. The multimeter will display the resistance value in ohms, indicating the wire's electrical resistance.
Electrical resistance in a wire depends on the wire's?
It's dependent on the wire's composition. That is, what material it is made of. <<>> The electrical resistance in a wire depends on the wire's length and cross sectional area.
What is an Grade an answer to what affects the resistance in a wire?
*the resistivity of the metal the wire is made of *thickness of wire *length of wire
What kind of wire would have the greatest electrical resistance?
A thin and long wire made of a material with high resistivity, such as nichrome or tungsten, would have the greatest electrical resistance.
What type of resistance would exist for electrical timers?
none the resistance is in the wire not the timer
A wire that is what would have the greatest electrical resistance?
A long and thin wire made of a material with high resistivity and low conductivity would have the greatest electrical resistance. The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area, so a long, thin wire will have a greater resistance compared to a shorter, thicker wire.
Why does a longer piece of wire have more electrical resistance than a shorter piece?
A longer wire has more electrical resistance because there is more wire material for the electrical current to pass through. This increased distance results in more collisions between the moving electrons and the wire atoms, which hinders the flow of current and creates more resistance.
What property wire increases when it is made thinner?
electrical resistance
