Wheatstone Bridge-   In 1843, a British physicist Sir Charles F. Wheatstone suggested a method to determine the value of an unknown resistance.   A Wheatstone Bridge is an arrangement of four resistances used to determine one of these resistances quickly and accurately in terms of the remaining three resistances.   Construction & Working-   […]

Heating Effect of Electric Current-   When an electric current is passed through a conductor, it becomes hot and its temperature starts rising. This is called as heating effect of electric current or Joule’s heating effect.   Here, electric energy converts into heat energy. Various appliances such as geyser, iron, heater etc work on this […]
