The above model wasn't realistic. Real circuits (especially the long wires in an inductor) have resistance. If I want to include that resistance in my model, the circuit would look this this: ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

The ac resistance in a cylindrical conductor can be rederived from a different perspective compared to the derivation provided in [6]. The model also intuitively illustrates the duality between ...
