Question
Following figure shows an ac generator connected to a "block box" through a pair of terminals. The box contains possible R, L, C or their combination, whose elements and arrangements are not known to us. Measurements outside the box reveals that e = 75 sin (sin ωt) volt, i = 1.5 sin (ωt + 45∘) amp then, the wrong statement is
Answer: Option B
:
B
Since voltage is lagging behind the current, so there must be no inductor in the box.
