At DC, the bottom circuit will look like a 1 kΩ resistor along with whatever resistance the inductor’s wire presents (probably not much). At some very high frequency, the inductor’s effective ...

and the receiver on the right is electrically connected to the inductor on the left. You can see this in the photo above in the form of the crossing yellow and red wires. Also, a wire is ...

The wire-wound inductors support high currents, save space, and work in extreme temperatures, making automotive PoC systems safer.
