Explanation Given info: The cross-sectional area of the wire is 5.25 × 10 − 4 m 2 and the length of the wire is 65 km . The resistivity of the aluminum is 2.65 × 10 − 8 Ω ⋅ m . Formula to calculate the resistance of a wire is, R = ρ L A Here, R is the resistance of the wire. L is the length of the wire. A is are of cross-section of wire. ρ is the resistivity of the wire material. Substitute 5.25 × 10 − 4 m 2 for A , 65 km for L , 2.65 × 10 − 8 Ω ⋅ m for ρ in above equation to find the resistance R of the wire

Temperature Variance of Resistance

Electrical resistance or simply resistance is the property of a material that opposes the free flow of electrons through it. The total amount of resistance to the flow of charges (or current) is affected by many factors like the length of the conducting …

Is work function of a metals surface related to surface energy and surface tension? What is the need to the work function component in the math of tension of metal surfaces that cannot be provided by existing equations of surface energy and surface tension? What are the key differences in each parameter and variables that allow for a differentiation of each function? What has a more significant meaning work function, surface tension or surface energy? Are there real differences and meaning? Please clarify and if possible provide examples . Does surface tension dependant on thickness of a metal or type of metal surface all having the same thickness? Clearly temperature has a profound change on surface tension what other variables besides temperature are key to surface tension. What if any is there a connection between crystal structure of the element and surface energy and tension? This is NOT a Assignment Question!!!
