After searching for a while on the internet, I must not be using the
right search words but can't seem to find information on impedances.

On a TV, what are the typical impedances for the rca audio outputs that
typically go to an amplifier? What is the typical impedance for the
output jack for earphones?

Thanks.

Took about 2 seconds to find this:

Helps if you spell "impedence" right, to start with...

Thanks, although it didn't answer my question. I guess 2 seconds
wasn't enough.

I searched with the correct spelling. I just mispelled it here.

But you just spelt impedance wrong !

Your spelling is actually correct.

"low"

a little lower.

Numbers are pretty meaningless in these applications. What's your REAL
question?

Typical output impedances of modern consumer audio
equipment ranges from a few hundred to a few
thousand ohms. (roughly 200~~2000 if you want numbers)

Typical input impedances of modern consumer audio
equipment ranges from several thousand to over 10000
ohms (5000~~20000 if you want numbers)

Output impedances of headphone outputs is a mixed
bag depending on whether you are talking about an
MP3 player the size of your finger, to a large integrated
amp or DVD player or something.

Note that your questions seem wierd without some context.
Modern consumer audio equipment is designed with low
enough output impedances, and high enough input impedances
that most people never have to even think about them. Which
is likely why your web search was not very productive.

Why do you ask?
