Speakers and amplifiers alike are usually rated around 8 ohms, but that's not always the case. If your receiver is rated at 6, for example, does that mean you can't connect 8 ohm speakers?

1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are supposed to resist current. What the heck ...
