An electric circuit consists of a battery of emf $$E$$, an inductance $$L$$ and a resistance $$R$$ in series. The switch $$S$$ is closed at $$t=0$$. The current in the circuit grows exponentially with time as depicted by curve 1. The values of the circuit parameters $$E$$, $$L$$ or $$R$$ are now somehow changed. The circuit is closed a second time and the growth of current $$I$$ follows curve 2. The following conclusion or conclusions may be drawn.
