Initially, an inductor carries a constant current. Then the current is brought to a new constant value twice as large. After this change, what has happened to the potential difference across the inductor? A) It is larger than before the change by a factor 4. B) It has the same nonzero value. C) It continues to be zero. D) It has decreased.
In a purely inductive AC circuit as shown in the figure, ΔVmax = 100 V.The maximum current is 8.00 A at 80.0 Hz. Calculate the inductance L.
In a purely inductive AC circuit as shown in the figure, ΔVmax = 100 V.At what angular frequency ω is the maximum current 1.50 A in rad/s when L = 24.9 mH?
