The resistance of 10\ \mathrm{ft} length of a 20\ \mathrm{mil} iron wire is 1.8 ohms. What is the resistivity of the iron? If the diameter of the wire increases, then the resistance. The length of a given cylindrical wire is increased by 100%. Due to this decrease...
4(b), the peaks of all composites appear at a higher temperature compared with that of the neat PVDF sample. This again indicates that IF-WS2 NPs have an effect in promoting the nucleation of the PVDF matrix upon cooling. The shifts in the peak positions of samples of various composite ...
The activation energy of all samples was estimated from the resistivity curves using the TAFF model. It has been revealed that the pinning properties and activation energy improve when the diffusion-annealing temperature increases for a convenient temperature and also the activation energies of Yb-...
