In the second problem u told conductivity as 8000 but u wrote 800(ohm-cm) -1

sir,can you provide lectures on topics that have been added in ECE ESE exam(technical section) like advanced electronics,advanced communication,basic electrical etc???

sir i think at 8.59 the value of conductivity=8000 and current density is 80A/sq of cm

sir, i have a confusion when we apply thermal energy then some time we say that electron which is present in valence bond they got enough energy and jump to conduction band and some time we say that covalent bond will broken and then e goes to C.B so my question is that when covalent will broken and when valence e will go to C.B after apply thermal energy

abhinav kumar breaking covalent bond means making a free electron, i.e that electron only goes to conduction band

hlo sir, in the above lecture u told that as we increase the temperature in semi conductors electron hole pair will be generated ,so without applying potential is it possible to have a current(beacuse electron hole pair generate current )

No free electrons in nacl means it will be insulator But current passes through salt water know sir??
