Various circuits are used to observe the phenomenon of self-induction. Among these are the circuits shownig Figures (a) and (h). III Figure (a), key K is initially opened and the current Ilows through the induction coil L and resistor R connected iu series. In Figure (h), key K is initially closed and the current branches on to `R and L.` In both circuits the resistance of the coil L is much lower than R. Can an induction emf be generated in either' one of these circuits that is higher than the emf of the DC source?
