WebSep 12, 2024 · The resistance of a coaxial cable depends on its length, the inner and outer radii, and the resistivity of the material separating the two conductors. Since this … WebIt helps if you see the power as the rate at which the energy from the battery is being converted to some other form of energy, which in case of a resistor is heat. As you rightly mentioned, current and resistance are inversely proportional.
thermodynamics - If heat is inversely proportional to resistance of …
WebAug 13, 2024 · Heat produced across a resistor can be computed by the following formulae H=I²Rt H= (V²/R)t Going by #1, heat is directly proportional to the resistance whereas going by #2 heat is inversely proportional to resistance. Which is the right formula to be applied … WebThe ohm is the common unit of electrical resistance, equivalent to one volt per ampere and represented by the capital Greek letter omega, Ω. The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. See resistivity. climbing mount rainier without a guide
Why does increasing resistance decrease the heat …
WebSep 12, 2024 · The resistance of an object also depends on temperature, since \(R_0\) is directly proportional to \(\rho\). ... The resistance between the two conductors of a coaxial cable depends on the resistivity of the material separating the two conductors, the length of the cable and the inner and outer radius of the two conductor. ... WebFeb 9, 2024 · Even one continuous wire will not get enough resistance to connect directly into the mains. And a thinner wire will just burn faster. With a graphite rod it is the reverse. The resistance is so high, that we would need to connect every rod in parallel to reduce the resistance sufficiently to use with the mains. WebSep 6, 2016 · Then the equation reads H = I 2 R t, which tells us that heat is directly proportional to resistance. The source of your confusion was that you used voltage, … climbing mount fuji tours
