Why doesn't the potential difference across an inductor increase over time?
For school, I was trying to solve a question that features a circuit with a resistor, an inductor, and a battery all connected in series. It then shows an increasing concave down graph of something vs. t - the graph started at the origin and had a horizontal asymptote at some positive value of x. The "something" could be:
A. The potential difference across the resistor
B. The potential difference across the inductor
and/or C. The current in the circuit.
I had reasoned that it would be all 3, because when an inductor is first connected to a battery at time t=0, it doesn't allow electricity to flow, but as time goes on, it allows more and more electricity to flow until it is essentially acting like a wire. Therefore, current will increase, and voltage will also increase across the entire circuit. However, when this problem was graded, it turned out that B was incorrect, and I was not told why. Why is this the case?
