Introduction

Hello friends! This is Himanshu and I am going to help you to cope up with all the problems you have in the "PCM" ie. Physics, Chemistry and Maths during your 11th standard. Soon I am going to post series of blogs regarding topics of class 11 and I will be explain these topics thoroughly. The blogs will come once in a week and will cover at least some parts of a particular topic from each subject.
Hope you will like it and don't forget to post your queries in the comments. Stay tuned.

Simple Harmonic Motion

SHM is a kind of periodic motion. We can say that all SHM's are periodic but all periodic motion are not SHM.  Conditions for SHM: The acceleration of the body or the particle should be proportional to the negative of displacement. The total Mechanical Energy of the system remains conserved. There must be a state of stable equilibrium. Equation of SHM Consider a particle revolving around a circular path of radius ''a''. with a constant angular velocity  ω. Let at time t=0, the particle is at the position A then the projection of the particle will be at the point B on the y-axis. So when the particle comes at the top the projection also comes at the top. Hence we can see that the particle is doing periodic motion but the projection is doing SHM. Hence the time period of the SHM is same as the time period of the circular particle. The derivation of the actual equation of the SHM is a bit complex and it is difficult for me to show it here so...

Semiconductors and Communication System

This chapter can be divided into following categories:- Classification Types of Semi-Conductors p-n junction diode Biasing of Diode Rectifiers Special Diodes (Zener, Photodiode, LED and Solar Cell) Transistors Logic Gates Communication System In the next few posts I will be posting in the same manner ie. (in bullets form) for your convenience and I hope that helps you in completing your syllabus. Classification Materials can be classified on the basis of conductivity as Conductors, Insulators and Semi Conductors. The basic difference among all the three is the difference of energy in between the Conducting and the Valence band. This can be seen here. Note- The range of conductivity should be kept in mind. For Semi-Conductors the energy difference is not very large but not even very less. So by providing proper conditions they can show conductivity. Types of Semi-Conductors Further we can say that there are two other types of semi con...
