You apply 10V to an inductor that has an inductance of L. The back emf produced will be L*(di/dt) but how do we get this quantity (di/dt)? When you were in school, you were taught charging and discharging of an inductor and capacitor but they were always in ...
Learn the formula, units, and types of the electric field with examples. Understand Coulomb's law and the method to create the electric field. Related to this QuestionWhy do induced currents oppose the change in magnetic flux that causes them? Explain why the emf induced in the conductor is ...
To derive the expression for the instantaneous value of the induced emf in an AC generator, we can follow these steps:Step 1: Define the angle between the magnetic field and the coil When a coil is rotated in a magnetic field w
