What does 'Induced EMF' mean? Describe clearly the principles of 'Self Induction' What is the unit of Inductance? A Coil has self-inductance if 0.25H. Calculate the induced EMF if the current changes from 100mA to 350mA in 25mS Calculate the inductance of a circuit in which an EMF of 30V is induced, when the circuit's rate of change is 200A/sec. Thanks - need help or answers asap.
