Nickel-Chromium Heater Wire - Temperature Rise vs. Amps

WebStrategy. (a) The resistance can be found using Ohm’s law. Ohm’s law states that V = I R, so the resistance can be found using R = V / I . (b) First, the resistance is temperature dependent so the new resistance after the resistor has been heated can be found using R = R 0 ( 1 + α Δ T). WebAnswer (1 of 3): an alloy of nickel and chromium melts at quite a high temperature but it has quite high resistance and quite good resistance to oxidation. Those properties together, make for a useful resistive heating element.
