Impedance Matching

In this video I explain why “impedance matching” is an important factor in maximising the transfer of power from a supply source to the load, or output.

If you are not confident about what “impedance” is, or how that relates to resistance, then please watch my last video “Impedance Explained” which can be found here:-

   • Impedance Explained.  

Following a viewer's comment I have now published a further follow up video which demonstrates how you could measure the output impedance of a laptop's headphone jack:-
