Physics Alternating Current MHT CET 2025

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

(A)increase in the first circuit and decrease in second
(B)increase in both circuits
(C)decrease in both circuits
(D)decrease in first circuit and increase in secondCorrect

Answer: (D)

Solution

For a pure inductor the reactance is , which increases with f, so the current decreases. For a pure capacitor decreases with f, so $I =
