In this video I compare similarities from the physical world that you can see and touch, to help share how I think about Impedance.

You will learn about “Opposing” forces called “Reactance” and how these, together with “Resistance” combine to form what we call “Impedance”.

Whilst I do go through some formulas, these are not the key intended purpose of the video. For many people, the formulas are not really important.

What is more important, is to be able to visualise in your mind exactly what is going on with AC circuits and to imagine that in a way that makes sense to you.

I hope the analogies I share, which I have picked up from others over the years, really help your thinking as much as it has me.
