Engineering Entrance Exam

In simple words, current electricity can be defined as the electric charge continuously moving from one place to another along a pathway. It is measured in amperes (A). Electric current is needed for electrical devices to work.

No, in fact, it is one of the easiest chapter of class 12 Physics. Other chapters which are considered comparatively easy are Ray Optics and Electric Charges and Fields.

In NEET exam, the weightage of Equilibrium is around 3% to 6% and in JEE Main exam, the weightage is 4% to 6.6%.

There are two conditions needed for equilibrium. The net force and net torque acting upon an object must be zero.

There are four types of equilibrium constants: Formation constants, stability constants, association constants, and binding constants.

It consists of concepts such as Le Chatelier's Principle, equilibrium constant, and factors affecting equilibrium. It is not considered an easy chapter.

A reversible reaction where rate of the forward reaction equals to the rate of the backward reaction is called the equilibrium. It results in constant reactants and products concentrations over time.

The sum of a magnetic field that passes through a given surface area is called the magnetic flux. The mathematic formula is? = BA cos (? ). 

Ohm's Law states that when the temperature remains constant, the current (I) flowing through a conductor is directly proportional to voltage (v), and inversely proportional to resistance (R).

The basic principle of the electromagnet is the electromagnetism. When the ferromagnetic iron core is coiled by a wire and a current is passed through the core, it produces a strong and magnetic field, and turns the setup into a magnet. By changing the current, one can change the strength of the mag
