Question
A resistor, inductor, and capacitor are connected in series across an AC generator set at a very low frequency. As the frequency is gradually raised, how will the amplitude of current through the circuit change?
The current will be large at first, and get smaller as the frequency is raised to a very high value.
The current will be small at first, and get larger as the frequency is raised to a very high value.
The current will be small at first, get larger as the frequency is raised, and then get smaller again as the frequency is raised further towards a very high value.
The current will be large at first, get smaller as the frequency is raised, and then get larger again as the frequency is raised further towards a very high value.
I am using a Series RLC circuit as a radio tuner, so that I can listen to a baseball game that is broadcast at 620kHz. What physical change could I make that would tune the radio to a different frequency?
Change the resistor.
Change the capacitance.
Change the inductance.
Change either the capacitance or the inductance.
The current will be large at first, and get smaller as the frequency is raised to a very high value.
The current will be small at first, and get larger as the frequency is raised to a very high value.
The current will be small at first, get larger as the frequency is raised, and then get smaller again as the frequency is raised further towards a very high value.
The current will be large at first, get smaller as the frequency is raised, and then get larger again as the frequency is raised further towards a very high value.
Explanation / Answer
1)
option 3)
The current will be small at first, get larger as the frequency is raised, and then get smaller again as the frequency is raised further towards a very high value.
2)
Change the capacitance.
