What is the Hysteresis Loop? Discuss Advantages of Hysteresis

WebbOne of the reasons for the hysteresis in Charge-discharge plot is poor kinetics. Such a poor kinetics is again related to diffusion of ions. So, if you reduce the grain size or improve … Acoustic absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body. The energy transformed into heat is said to have been 'lost'. When sound from a loudspeaker collides with the walls of a room part of the sound's energy is re…
