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 of the conductor […]

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 discussed- 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 […]

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 due to which it opposes the motion of charge carriers inside it. The collisions of free electrons with the positive metal ions […]

Combination of Cells-   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 cells is called as a battery.   Cells may be connected in the following styles-     Series Combination Parallel Combination Mixed Combination   […]

Electric Cell-   A cell is a device which supplies energy to charge carriers and thereby maintain their flow in the electric circuit.   By using chemical reactions, a cell produces potential difference across its terminals. When the terminals of a cell are connected by a wire, the potential difference between the terminals of cell […]
