Resistivity-   Before you go through this article, make sure that you have gone through the previous article on Resistivity of Conductor.   We have learnt- Resistivity of a conductor is defined as the resistance of a unit cube of the material of the conductor. It depends upon the nature of material and temperature of […]

Combination of Cells-   Before you go through this article, make sure that you have gone through the previous article on Series Combination of Cells.   We have learnt- A single cell provides a feeble current. In order to get a higher current in the circuit, we use a combination of cells. A combination of […]

Resistance-   Before you go through this article, make sure that you have gone through the previous article on Resistance of Conductor.   We have learnt- Resistance of a conductor is the property by virtue of which it opposes the motion of charge carriers through it. The collisions of free electrons with the positive metal […]

Electric Cell-   Before you go through this article, make sure that you have gone through the previous article on Electric Cell.   We have learnt- An electric cell is a device which supplies energy to the charge carriers and maintain their flow in the electric circuit. An ideal cell has zero internal resistance whereas […]

Electric Cell-   An electric cell may be defined as-   An  electric cell is a device which supplies energy to the charge carriers and thereby maintain their flow in the electric circuit.   Working of Electric Cell-   By using chemical reactions, a cell produces the potential difference across its terminals. When the terminals […]
