## Homework Statement

Suppose you are developing a high-fidelity soundsystem. If you wish to deliver low-freq signals to a woofer, what device would you place in series with it?

A) Resistor

B) Capacitor

C) Inductor

## Homework Equations

## The Attempt at a Solution

According to my book, the answer is an inductor; however, I would have thought that it would be a resistor if because that's how a low pass filter is made. My book references the equation I0 = V0/(wL) when giving the answer. I'm not quite sure why it would be an inductor? Couldn't it be a resistor just as easily?
