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?

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

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.
