JEE · NEET Previous Year Question

Same current is flowing in two a.c. circuits. First contains only inductance and second contains only capacitance. If frequency of a.c. is increased for both, the current will

Topic: JEE PYQ

Answer: D. Full step-by-step solution below.

  1. Aincrease in first circuit and decrease in second
  2. Bincrease in both circuits
  3. Cdecrease in both circuits
  4. Ddecrease in first circuit and increase in second

Correct answer: D

Solution

(d)

Inductive reactance,
When frequency of a.c. source is increased, inductive reactance increases while capacitive reactance decreases. Also, Current
So, current in inductive circuit decreases and in capacitive circuit increases on increasing the frequency of a.c. source.
