In this video I follow up on a viewer’s comment that was posted on my “Impedance Matching” video (link below).

   • Impedance Matching  

The comment asked to demonstrate how you would go about measuring the Output Impedance of a laptop’s headphone jack.

Using a standard Multimeter, a resistor and a bit of ohms law, I demonstrate how this is achievable.

If you are uncertain about what impedance is, then you may find it useful to watch my “Impedance Explained” video here:

   • Impedance Explained.  

I also make reference to Voltage Divider circuits, which were previously explained in my “What Are Voltage Dividers” video here:

   • What Are Voltage Divider Circuits?
