In a home stereo system, low sound frequencies are handled by large "woofer" speakers, and high frequencies by smaller "tweeter" speakers. For the best sound reproduction, low-frequency currents from the amplifier should not reach the tweeter. One way to do this is to place a capacitor in series with the 9.0 Ω resistance of the tweeter; one then has an RLC circuit with no inductor L (that is, an RLC circuit with L = 0). What value of C should be chosen so that the current through the tweeter at 200 Hz is half its value at very high frequencie

Question
In a home stereo system, low sound frequencies are handled by large "woofer" speakers, and high frequencies by smaller "tweeter" speakers. For the best sound reproduction, low-frequency currents from the amplifier should not reach the tweeter. One way to do this is to place a capacitor in series with the 9.0 Ω
resistance of the tweeter; one then has an RLC
circuit with no inductor L
(that is, an RLC
circuit with L
= 0).
What value of C
should be chosen so that the current through the tweeter at 200 Hz
is half its value at very high frequencies?
