>> How do you explain to your kids what your dad does at work? Immediately you will read the university course or "rejected, small, you will still not understand"?

Not quite in the subject, but suddenly I remembered how I was explained about the power of the current, and other electrical circuits:

Imagine a long tunnel, well, like a subway, filled with people standing in place. These are electrons in the conductor.

From one side of the tunnel comes a huge monster. It is tension.

The size of this monster and the degree of its horror, directly affect the speed of stumbling people from it through the tunnel. It is the power of current.

Because the width of the tunnel is limited, the rear rows are forced to pin on the front rows, which are not so scary yet, creating a dungeon and local battles. It is resistance.

If a concrete wall met in the tunnel with a door that barricades the path and narrows the passage, it is a resistor.

If a hole with a width equal to the width of a tunnel is formed, it is a condenser.

If there is ice on the floor of the tunnel, allowing the rear rows to push people on the ice easily and freely, it is an inductivity coil.
