When the frequency of an ac circuit is decreased, the current in the circuit increases. which combination of elements is most li
zaharov [31]

Answer:

The combination of elements most likely to comprise the circuit are resistor, inductor and capacitor

Explanation:

The impedance of an LCR circuit shown as

     Z = √R² + (X↓l - X↓c)²

     Z​ = √R² + (2π∨L - 1/2π∨c)²

Variation of Z with respect to υ is shown in the figure.

As υ increases, Z decreases and so the current increases.

At υ = υ↓r

Z is minimum, current is maximum. Beyond

    υ = υ↓r

​Z increases and so current decreases.

so the combination of circuit elements that is most suitable to comprise

the circuit is R, L and C.
