Inductance

Question 1 of 10

An inductor has a self-inductance of 1H when

  1. a current of 1A through the inductor produces a p.d. of 1V across its terminals
  2. a current of 1A through the inductor produces a p.d. of 1V across another inductor
  3. a rate of change of current of 1A/s in the inductor induces in it an e.m.f. of 1V
  4. a rate of change of current of 1A/s in the inductor induces in another inductor an e.m.f. of 1V
