NEET

There are two types of electricity - Static and Current electricity. The electric charges buildup on a material's surface is called the static electricity. The continuous flow of electric charge is termed as the current electricity. Current electricity is of two types - Alternating Current (AC) and Direct Current (DC). In AC, the charge direction reverses periodically and in DC, charge flows in one direction.

The current's SI unit is ampere. The symbol for ampere is A. The term ampere is named after the French physicist André-Marie Ampère.

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 (? ).
