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.
The resistance of a certain wire is 20 Ohms. Another wire of the same material has a diameter 1/3 as great and twice the length. What is the resistance of the second wire?
the resistance of a wire is 25 ohms. another wire of the same material and same temperature has a diameter twice as great and length six times as great. find resistance of the second wire? answer is 16.67 ohms solution please
A wire of initial length Ly and radius to has a measured resistance of 2 Ohms. The wire is drawn under tensile stress to a new uniform radius of r-0270 What is the new resistance of the wire? Hint: Assume the radius and the length of the wire can change. 1.250 Ohms 1875 Ohms 69444 Ohms 3,375 Ohms None of the above
A wire of initial length L0 and radius r0 has a measured resistance of 2 Ohms. The wire is drawn under tensile stress to a new uniform radius of r = 0.2r0. What is the new resistance of the wire? Assume the radius and the length of the wire can change (Assume the radius and the length of the wire can change) 3375 Ohms 69444Ohms 1875Ohms 1250Ohms
A Si wire of diameter 2μm and length 200 micrometers has a resistance of 1000 ohms. Determine the resistivity of that Si in terms of ohm-cm. Suppose you make the same wire using copper, what should be its resistance?
A length of AWG #12 copper wire has a resistance of 0.020 Ohms at 20 °C. Calculate the temperature for which the resistance is 0.023 Ohms.
A one meter section of circular cross-section wire has a resistance of 382 Ohms. If you stretched the wire (while maintaining a circular cross-section), how long would the wire have to be to have a resistance that is 48.8 times as large? Don't round. The answer should be 6.99 but I need steps to understand the answer.
The resistance R of a wire varies directly with the length L of the wire and inversely with the square of its radius r. A wire with a length of 350 cm and a radius of 0.4 cm has a resistance of 16 ohms. Determine the resistance of a 500 cm piece of similar wire with a radius of 0.35 cm. Round your final answer to four decimal places and be sure to include units.
A wire with a resistance of 6.0 ohms is drawn out through adie so that its new length is three times its original length. Findthe resistance of the longer wire, assuming the resistivity anddensity of the material remain the same.HELP!!!!!!!!!!!
