A radio contains a series RCL circuit with a 250 mH inductor, a 2.8 microF capacitor, and a 960 Ohm resistor (the speaker). When plugged into an AC wall outlet in the US, the speakers output is 15 W. If the radio is plugged into 40.0 Hz, 180-V rms AC outlet in another country, will the speaker be louder or softer than in the US (which uses a different frequency and rms voltage)?
Homework Answers
If the frequency and voltage of AC outlet is different from one country to another country. So, speaker not working.
