May 06, 2013 · Photosynthesis is the process of transforming sunlight into chemical energy by storing it in the bonds of glucose or sugar. This process occurs in plants, bacteria and some protists, or algae to produce sugar as food. The chlorophyll present in leaves of photosynthetic plants captures energy from sunlight and converts it to carbohydrates. Examples of this might be when you turn a hand crank to power a simple generator (Forms of Energy, par. 21), or when an electric generator converts electricity from mechanical energy. It forces an electric charge to flow through an external electrical circuit.
Oct 28, 2020 · Electrical power transformer thus plays a vital role in power transmission. Two winding transformers are generally used where ratio of high voltage and low voltage is greater than 2. It is cost effective to use auto transformer where the ratio between high voltage and low voltage is less than 2.
