MOTION MOTION , THERE DIFFERENT TYPES, AND EQUATIONS OF MOTION . Motion – Rest and Motion -An object is said to be in rest , if body does not change its position with time , with respect to surroundings . An object is said to be in motion , if body changes its position […]
Mutual induction- In this topic students will study what is mutual induction and coefficient of mutual induction / mutual inductance? And what is the unit of mutual inductance Mutual induction- Let us consider two coils placed near to each other closely . One of the coil carries the battery is the primary coil and the […]
Errors of measurement- generally it is seen the measured value of a quantity is different from its actual value . this difference in the measured value and and the true value of a quantity is called error of measurement. Errors of measurement can be divided into following types- Systematic errors -Those errors whose causes are […]
Significant figure In this topic we will discuss what is a significant figure ? how can we find the significant figure in the given values and what are the rules for counting significant figure ? Significant figure – It is the measured value of a physical quantity tell the number of digit in which we […]
Define 1 Ampere This topic only explain the term definition of Ampere ( which is explain in different-different type . Students can learn it according to there needs. ) Ampere is the basic unit of electric current . It is named after Andre-Marie -Ampere a French scientist born in 1775 . He also known as […]
ELECTRIC CURRENT or CURRENT ELECTRICITY electric current – Electric current – When electric charges is in motion , they constitute what is called an electric current . electric current is defined as the rate of flow of charge through an area of the conductor . if Q is the charge flows through a conductor […]
SELF-INDUCTION OF LONG SOLENOID SELF-INDUCTION OF LONG SOLENOID this topic is important for the class 12th board examination Self-inductance of long air-cored solenoid question may asked as – what do you mean by the term self-induction ? Find expression for the self-inductance of long air cored solenoid . Self-inductance of long air-cored solenoid – Suppose […]
Explain the term self-induction of a coil Self – Induction – It is the property of an electric circuit or coil by virtue of which it opposes any change of flux or current in it by inducing a current in itself is called self- induction. In another words we can say “self-induction is the inertia […]
What is electric current What is electric current ? what is its unit ? define Ampere. Electric current-When electric charges is in motion , they constitute what is called an electric current . electric current is defined as the rate of flow of charge through an area of the conductor . if Q is the […]
Faraday’s law of electromagnetic induction Electromagnetic induction – As we know when electric current passes through a conductor then magnetic field developed across the conductor , first discovered by Oersted . But Michael Faraday found its converse is also possible i.e. Whenever magnetic field changes around a coil ( and hence magnetic flux linked across […]
