Here's your Shmoop dujour, brought to you by audio equipment for dogs.

00:09

They're generally most interested in woofers.

00:34

What is this question really asking?

00:36

We're told that the output impedance of the amplifier should be 1/8 or less of the speakers.

00:42

The speakers have an impedance of 6 ohms. What's 1/8 of 6?

00:47

We can get that without knowing what impedance is or what ohms are.

00:59

A lot of times these questions will throw curveballs at you with these fancy terms you don't need to know. Just do the math.

01:06

Because want to know the maximum output, this has got to be the upper limit.

01:11

Since we want this answer in the form of an actual number of ohms (i.e. a decimal) rather than a fraction,

01:16

we just take six divided by eight or take a simplified version of 3/4.

01:29

Ohm sweet ohm.
