What else can I help you with?
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.
Which has greater resistance a thick wire or a thin wire of the same lenght?
The thin wire has more resistance to the flow of electric current than the thick wire. If you connect the wires to a battery the battery will supply electrical pressure (voltage) and the wires serve similar to pipes that conduct water under pressure. A small pipe exhibits more resistance to the flow of water and a thin wire exhibits more resistance to the flow of electrons. However, as you point out different wire materials exhibit different resistances for equal sizes (silver conducts better than copper, etc.).
Can copper and alluminium wire of same length and diameter have same resistance?
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
What happens to the resistance of the conductor if the conductors become longer but the diameter stays the same?
If the length of the conductor increases while the diameter remains constant, the resistance of the conductor will increase. Resistance is directly proportional to the length of the conductor, so a longer conductor will have higher resistance. The diameter, however, does not directly affect resistance as long as it remains constant.
What type of relationship exists between the length of a wire and the resistance if all other factors remain the same?
In general, the resistance of a wire is directly proportional to its length. This means that as the length of the wire increases, the resistance also increases, assuming all other factors such as material, cross-sectional area, and temperature remain constant.
Which has the greater resistance thick wire or a thin of the same length?
The thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal resistance.
What happens to insulation resistance when increasing cable length?
The insulation resistance remains the same throughout the entire length of the conductor.
Is a wire thick with low electric resistance?
A wire that is thicker than another wire of the same material has less resistance
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.
Do parallel cables of the same length carry the same current?
yes in case the two cables have same resistance

The resistance of an extension cord varies directly with the length of the cord?
This means that as the length of the extension cord increases, the resistance also increases. Similarly, if the length decreases, the resistance will decrease as well. This relationship is described by the equation R = kL, where R is the resistance, L is the length, and k is a constant.
is it construct two wires of the same length one of copper and one of iron that would have the same resistance at the same temperature?
Yes, it is possible to construct two wires of the same length, one of copper and one of iron, that have the same resistance at the same temperature. The resistance of a wire is determined by its resistivity, length, and cross-sectional area, as given by the formula ( R = \frac{\rho L}{A} ). Since copper has a lower resistivity than iron, the copper wire would need a larger cross-sectional area than the iron wire to achieve the same resistance.
What are some quick hairstyles for thick shoulder length hair?
I have the same length as you, and my hair is thick also. What I would suggest: Straighten it Curl the ends under Putting a headband in Wearing it down Hope these work for you!

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.
