WebTask number: 2113. Electrical resistance of a wire with a circular cross-section of a diameter of 0.5 mm is 2 Ω. The length of the wire is 8 m. How long should be a wire of the same material but with the radius twice as big, so that the resistance of the wire is also 2 Ω? Determine the resistivity of the material, of which the wire has been made. WebA A wire of resistivity ρ must be replaced in a circuit by a wire of the same material but four times as long. If, however, the total resistance is to remain as before, the diameter of the …

WebThe 12-gauge wire has a diameter of 1/12 inch while the 14-gauge wire has a diameter of 1/14 inch. Thus, 12-gauge wire has a wider cross section than 14-gauge wire. A 20-Amp circuit used for wall receptacles should be wired using 12-gauge wire and a 15-Amp circuit used for lighting and fan circuits should be wired using 14-gauge wire. margaret beaufort war of the rosesWebFeb 28, 2024 · A circular cross section core will naturally have a smaller inner radius and, because of this, it will tend to magnetically saturate a little bit more at that inner radius … kuma the bear gameWebDec 22, 2024 · We can now substitute our acquired cross-sectional area value from Eq.
