Answer to: Find the resistance of a wire of length l whose radius (r) varies linearly from a to b. The resistivity of wire's material is \rho. By...
Cross-Sectional Area and Resistance:The cross-sectional area of the wires has a direct effect on the amount of resistance. Wider wires have a larger cross-sectional area, and the wider the wire, the less the resistance to the flow of electric charge. When all other variables are left unchan...
If a wire is stretched to double its length, what will its new resistance be?Question:If a wire is stretched to double its length, what will its new resistance be?Resistance:It is defined as the property of a material to show hindrance against the current flowing in the...
In a high soil resistivity area, counterpoise wires are applied to decrease the grounding resistance of tower grounding devices. If the conductor of counterpoise wire is very long, although the power frequency grounding resistance of the tower grounding device is decreased, the lightning protection per...

Why is the EMF induced, per the formula E = BLV, calculated with L as the length of the wire frame, instead of the length of the rod? Don't charges throughout the rod (including in the parts beyond the wire frame) move due to a Lorentz Force qvB, so EMF = work...

Answer to: A wire has resistance R. A second of wire has twice the length, twice the diameter, and twice the resistivity of the first wire. What is...
Why is it necessary to measure the average resistance/unit length of the wire? What is elastic after effect? Can you think of an experiment to verify length contraction directly? Explain. Suppose that a steel bridge, 1000 m long, was built without any expansion jo...
