In the simple L-R circuit, can the emf induced across the inductor ever be greater than the emf of the battery used to produce the current?

Solution

In L-R circuit, the emf equation is $E = V_{R} + V_{L}$ where $E =$ emf of battery, $V_{R} =$ potential across resistance R and $V_{L} =$ potential across inductor L.
So, $V_{L} < E$
