A wire of length L and cross-sectional area A has a resistance of 5 Ω. What is the resistance if the same amount of material is used to make a wire triple as long?
A wire of length L and cross-sectional area A has resistance R. What will be the resistance Rstretched of the wire if it is stretched to twice its original length? Assume that the density and resistivity of the material do not change when the wire is stretched.
One copper wire has a cross sectional area of A and resistance R and length L. A second copper wire has a length L and cross-sectional area 2A. What is the resistance of the second wire in terms of R? R/2 R 2R 4R Some other value
Two copper wires have the same length but different cross sectional areas. The cross-sectional area of wire 1 is A, and that of wire 2 is 2A. How are the resistances of the two wires related? Choose the correct answer from the following choices. Wire 1 has four times the resistance of Wire 2 Wire 1 has half the resistance of Wire 2 The are the same. Wire 1 has twice the resistance of Wire 2
A copper wire of length L and cross-sectional area A has a resistance of R0. What is the resistance of another copper wire with length 6L and cross-sectional area 2A. Give your answer as a multiple of R0. A 18.00 R0 B 0.33 R0 C 6.00 R0 D 3.00 R0 E 1.50 R0
two copper conductors have equal length. the cross-sectional area of one conductor is three times that of the other. If the resistance of the conductor having smaller cross-sectional area is 20 ohms, what is the resistance of the other?
What is the resistance per meter of an gold wire with a cross-sectional area of 2.4×10−7 m2 . I used ----- (Resistance)/(cross sectional area) and (2.44* 10^-8) / (2.4 *10^-7 ) but it is wrong... Thank you for the help in advance!
The resistivity of a conductor depends on A. It’s cross-sectional area B. It’s length C. The material out of which it is composed
