For simple cireeit current ;vintage and resistance etcetera. Can be determined for individual circeeit element by using ohm's low. But for complex cerceeit it is difficult so Kirchhoff formulated two rule

Vaibhav Srivastava 6 years, 3 months ago

Kirchoff current law stares that the current flowing through the node (or a junction) is always equals ti the current flowing outside. Kirchoff voltage law states that the sum of all the voltages inside a circuit is equals to zero.

Actually emf is also voltage....but it is measured when no current is drawn from battery i.e. battery/cell is fully charged. Thats why emf is always greater than voltage..

Abhishek Kumar 6 years, 3 months ago

How emf is induced in cell

Vidit Aggarwal 6 years, 3 months ago

The nuclear force has the following properties: 1) The strong nuclear force binds protons and neutrons in a nucleus. The weak nuclear force appears only in certain nuclear processes such as beta decay. 2) Strong nuclear force is the strongest force in nature. It is about 100 times stronger than electromagnetic force. Weak nuclear force is stronger than the gravitational force but weaker than the electromagnetic or strong nuclear force. 3) It is a short-range force and is operative only over the size of nucleus. 4) Strong nuclear force is responsible for the stability of nuclei.

I don't know but i am trying to solve previous year's exam paper and i don't think that the physics paper is so difficult if your all concepts are clear in physics and you solved question on them . Then you will find the paper easier .
