Electrical energy is produced by converting solar energy using photovoltaic cells. Photovoltaic cells directly convert sunlight into electricity through the photovoltaic effect. When sunlight hits the cells, it excites electrons, generating a flow of electricity.
Dynamo converts mechanical energy into electrical energy. Rotating coils within a magnetic field induce an electromotive force, generating electrical current. This process is based on electromagnetic induction.
Energy is produced in the Sun by nuclear fusion. In the Sun’s core, hydrogen nuclei fuse to form helium nuclei, releasing immense amounts of energy in the process. This fusion reaction powers the Sun and generates the heat and light ...
Food gets cooked in less time in a pressure cooker because high pressure increases the temperature of boiling water. The elevated pressure inside the cooker raises the boiling point of water, allowing food to cook at higher temperatures, thereby reducing ...
