Resistivity of a wire experiment results
WebThe resistance of a wire depends on the length of the wire, the cross-sectional area (A), and the resistivity (ρ) of the material: R = ρ L/A (2) A plot of R vs. L will result in a straight line … Webfor SMA-AM based on the investigation of SMA electrical resistivity (ER). Firstly, an ER transformation kinetics model is proposed based on the simulation of SMA differential scanning calorimetry (DSC) curves. Then a series of thermal-electrical-mechanical experiments are carried out to verify the validity of the ER model, whereby the SMA-AM
