What has a lower resistance a long thin iron wire at high temp or a short thick copper wire at low temp?
A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.
What is the benefits of using low resistance wires to transport electricity?
Low resistance wires allow for more efficient transfer of electricity as less energy is lost due to heat production. This can result in reduced energy costs and overall improved performance of the electrical system. Additionally, low resistance wires can help to reduce the risk of overheating and potential hazards such as fires.
What resistance of a connecting wire is less than the resistance of a resistor?
The resistance of a connecting wire that is less than the resistance of a resistor would depend on the materials and dimensions of the wire and resistor. Generally, most connecting wires have very low resistance compared to resistors. Copper wires, for example, have low resistance and are commonly used for connecting circuits.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A high-resistance bulb typically has a thicker filament compared to a low-resistance bulb. The thicker filament in a high-resistance bulb can withstand the greater heat generated by the increased resistance, resulting in a longer lifespan for the bulb.
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.
How can you get low viscoSity and high resistance?
You get low viscosity with thin liquids like water that flow easily. Low viscosity means the liquid has low resistance. You get high resistance when you have liquids that flow slowly like honey and syrup, which means high viscosity.
Why do spark plug wires have resistance?
All wires have a resistance, as does everything else in the universe. Conductors like metal and carbon generally have low resistances where as non conductors have a very high resistance. Think of it like friction, but electric.
Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
Is graphite a high resistance or low resistance of electricity?
Graphite is low resistance of electricity...
What is the viscosity definitions?
Viscosity is a fluids resistance to flow. A high viscosity fluid would be thick, a low viscosity fluid would be thin.
What is ment by high resistance and low resistance on a meter?
On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.
Do meters usually have a high or low internal resistance?
It depends on the application. Voltmeters have a high internal resistance, while ammeters have a low internal resistance.
What has a lower resistance a long thin iron wire at high temp or a short thick copper wire at low temp?
A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.
What is high resistance and low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.

What wire connection better high or low resistance?
Usually low resistance is better.
