Semiconductors (Part-1) | Revision Checklist 53 for JEE & NEET Physics

Warning⚠️ At 2:30 on increasing the temperature, resistance will increase in conductors (Because alpha is +ve) Hope sir will add this in discription or pin a comment 🙏

No resistance will decrease because the kinetic energy of electrons will increase because of bonds are now weaker than the original one.
