Question

What corresponds to the natural frequency of oscillation of a swing in an LCR circuit?

Options

• The minimum impedance \[Z_{\min}\]

• The natural resonant frequency \[\omega_0\]

• The resistance \[R\]

• The maximum current \[i_{\max}\]

Answer 1

A swing has a natural frequency of oscillation. The corresponding electrical quantity is the LCR circuit's natural resonant frequency \[\omega_0\].
