In a series resonant circuit, what is the effect of doubling the inductance while halving the capacitance?

Show Answers

The peak current at resonance will be alteredThe circuit's resonance frequency will be affectedThe impedance at the resonance point will varyThe circuit's ability to select frequencies will improveNo significant change will occur

Explanation

Doubling the inductance and simultaneously halving the capacitance does not affect the resonance frequency, maximum current, or impedance at resonance. However, these changes enhance the circuit's selectivity, meaning it becomes better at distinguishing between closely spaced frequencies.
