Same current is flowing in two alternating circuits. The first circuit contains only inductance and the other contains only a capacitor. If the frequency of the emf of AC is increased, the effecton the value of the current will be

Options

  1. Aincreases in the first circuit and decreases in the other
  2. Bincreases in both the circuits
  3. Cdecreases in both the circuits
  4. Ddecreases in the first circuit and increases in the other

Correct answer

D. decreases in the first circuit and increases in the other

Step-by-step solution

I_ L = V X_ L and I_ C = V X_ C ie, I_ L 1 and I_ C with increase in , I_ L decreases while I_ C increases.
