Basic electricity is described in many ways. When an electric circuit flows through a conductor, a magnetic field (or "flux") develops around the conductor. The highest flux density occurs when the conductor is formed into a coil having many turns. In electronics and electrical technology, a coil is usually known as an inductor.
Apr 24, 2020 · minimum energy of an electron can have in this atom is 3.4 eV . It has given that a hydrogen atom is 5.3 × 10¯¹¹ m in radius. we have to find the minimum energy of an electron in this atom using Uncertainty Principle. from Heisenberg's uncertainty principle, ∆P × ∆x ≥ h/4π . here, take ∆x = 5.3 × 10¯¹¹ m , h = 6.63 × 10¯³⁴ Js
Feb 24, 2021 · when potential energy increases, kinetic energy decreases. Thus, at maximum potential energy kinetic energy is zero. Total energy (E) is sum of kinetic energy and potential energy. T.E = K.E+ P.E. T.E = Thus, on doubling the potential energy the overall energy of the SHM will will remain the same. Hence, option d is correct.
Jun 19, 2020 · Mass of object (m) = 2.5 kg. Speed of object (v) = 2 m/s. As we know that , The amount of energy stored in an object due to its motion is called kinetic energy. Kinetic energy = (1/2) mv². The SI unit of kinetic energy is joule. Thus , Find an answer to your question Work out the kinetic energy of a 2.5 kg remote-controlled car that is moving ...
Sep 3, 2016 · If we save some energy then all those are consumed less to satisfy the needs of the nation. The saved inputs and factors could be used for producing more energy. Also saved energy implies less demand. Or, using less energy enables the government to satisfy a higher demand or the same demand over a larger clientele. Measures to conserve energy: 1.
Jan 14, 2018 · nuclear energy is the hope of future. 1. people in India are mostly dependent on conventional sources or energy which can easily get depleted. 2. these conventional sources produce pollution as well. 3. nuclear energy doesn't produce pollution if radioactive material is disposed safely. 4. tremendous amount of energy is generated by nuclear ...
Electromagnetic induction is a fascinating and vital concept shaping how we generate, transfer, and utilize electricity. Its underlying principles, Faraday's Law and Lenz's Law, explain the phenomena occurring when magnetic fields interact with conductors. At the same time, its various applications, such as electric generators, transformers ...
Energy: The ability to do work. Energy = Power x Time. Energy Management System: A system designed to ensure safety, security, and reliability to an electrical network. A system in which a dispatcher can monitor and control the flow of electric power by opening and closing switches to route electricity or to isolate a part of the system for ...
May 13, 2020 · The total amount of energy transferred by a kettle electrically = 6000 J. Amount of energy wasted = 1500 J. To find, The efficiency of the kettle. Solution, We can simply solve this numerical problem by using the following process: Mathematically, Efficiency = (total amount of supplied energy used)/(total amount of supplied energy) × 100. Now,
An electron as de Broglie wavelength 2.0×10^-12m.find the kinetic energy also find the phase and group velocity of its de Broglie waves. - 5986917
