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 […]

Parallel Combination of Cells | Formula
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 […]
Temperature Dependence of Resistance
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 […]
Series Combination of Cells | Formula
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 […]
Cells & Batteries | EMF | Terminal Voltage
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 […]
