E xplain self-inductance . D efine inductance in terms of induced voltage. C ite the units of measure for inductance. D escribe the voltage waveform across an inductor when a sine waveform of current is being applied. D efine the term mutual inductance .
E xplain the meaning of coefficient of coupling .
I O N Coefficient of Coupling Two conductors or coils are said to be coupled when the are arranged so that a changing magnetic field created by one of the coils can induce a current in the other coil. There is no such thing as perfect coupling, however a good transformer with an iron core will have a value of k that is close to 1.
