SiC is poised for significant growth, driven by its advantageous properties and emerging applications: The earliest electrical application of SiC was as a surge protection in lightning arresters in electric power systems. These devices should show high resistance until eventually the voltage across them reaches a particular threshold VT at https://www.quora.com/profile/Trevor-Flatcher-2/Role-of-Silicon-Carbide-in-Fuel-Cells-Silicon-carbide-SiC-plays-a-crucial-role-in-advancing-fuel-cell-technology-off
