CBSE has been at the forefront of the progress in the educational field in all India. In his boards exams chapters Physics topic of Solids and Semiconductor Devices read officially as they manage exams of it’s. Solids and Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications. They use electronic conduction in the solid state as opposed to the gaseous state or thermionic emission in a high vacuum. For boost your knowledge mostly helpful questions answers Mcqs test available for take practice online.
