Question 12 At room temperature, free electrons in a p-material......... are the majority carrier. are the minority carrier. are in the valence band. O do not exis

Answer 1

Q-12

At room temperature free elecrtons gain sufficient energy to move from valance band to conduction band at leaves a hole at its place, in p type material holes are majority cahrge carrier and elecrons are minority charge carriers. at room temp holes will be majority charge carries and free electrons are minority charge carriers.

is = 5 Halim Given that, total impidence of aftu circuit R=3 Kohm, X = Groh Find X in ohms. and I in thery. Solution total Impedance of the [ir [unt = 5 = R + j(XL-XE). = 5 kotim. 5 = r R² + (x1 - xc)2 5 = (3) 2+ (X2-6)2 5 = 59+ (XL-X[1² 25= 9+ (XL-6)? 16 = (XL-6)2 XL - do kohm. X = 10,000 ohm.
