What happens to inductor when switch is closed? When the switch is first closed, the current through the inductor is zero, because it cannot change instantaneously. This means that the inductor acts like an open circuit, so all the voltage is across the inductor. The changing magnetic field creates a back emf which acts to […]

Is the paper peer-reviewed? Who is a scientist? Are there any other explanations? How was […]
What are the three main physical properties of sound waves?
What are the three main physical properties of sound waves? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. […]
