Question
Resonance is a very special condition in an AC circuit. The resonance frequency is the natural oscillation frequency of the circuit itself, so when the source frequency equals the resonance frequency some special things happen.1.For a particular set of R, L, and C values, the current in the circuit is maximized when the circuit is at its resonance frequency.
2.For a particular set of R, L, and C values, the current in the circuit is minimized when the circuit is at its resonance frequency.
3.For a particular set of R, L, and C values, the impedance Z of the circuit is maximized when the circuit is at its resonance frequency.
4.For a particular set of R, L, and C values, the impedance Z of the circuit is minimized when the circuit is at its resonance frequency.
5.For a particular set of R, L, and C values, the magnitude of the phase angle is zero when the circuit is at its resonance frequency.
6.For a particular set of R, L, and C values, the magnitude of the phase angle is 90 degrees when the circuit is at its resonance frequency.
7.For a particular set of R, L, and C values, the power dissipated in the circuit is maximized when the circuit is at its resonance frequency.
8.For a particular set of R, L, and C values, the power dissipated in the circuit is minimized when the circuit is at its resonance frequency.
Explanation / Answer
