Initially, an inductor with no resistance carries a constant current. Then the current is brought to a new constant value twice
as large. After this change, when the current is constant at its higher value, what has happened to the emf in the inductor?
Rank the following inductors in order of the potential difference Vab , from most positive to most negative. In each case the inductor has zero resistance and the current flows from point a through the inductor to point b. (i) The current through a 2.0 mH inductor increases from 1.0 A to 2.0 A in 0.50 s; (ii) the current through a 4.0 mH inductor decreases from 3.0 A to 0 in 2.0 s; (iii) the current through a 1.0 mH inductor remains constant at 4.0 A; (iv) the current through a 1.0 mH inductor increases from 0 to 4.0 A in 0.25 s.
8. A constant voltage of 5.00 V has been observed over a certain time interval across a 2.20 H inductor. The current through the inductor, measured as 2.00 A at the beginning of the time interval, was observed to increase at a constant rate to a value of 8.00 A at the end of the time interval. How long was this time interval?
