Imagine a scenario where a coil has an inductance of 2 H. If the current changes from 3 A to 7 A over a period of 2 seconds, what is the EMF induced due to self-induction?
💡 Hint: Apply the formula carefully and compute the rate of change.
Two coils are positioned such that a changing current in the primary coil results in an induced EMF in the secondary coil. If the current in the primary coil changes at a rate of 5 A/s, calculate the induced EMF in the secondary coil assuming it has a mutual inductance of 0.75 H.
💡 Hint: Consider the relationship defined for mutual inductance.
