| The battery in your cell phone right now is in some non-zero way
| also powering the lights in your room. Each keypress on your
| keyboard registers in the heater of your neighbors coffee
| machine. They're all part of the same singular universal circuit.

| Veritasium just ran with this pedantic tidbit to make a flashy
| controversial video. Which he didn't even get fully right because
| like Electro pointed out, there is always non-zero current
| flowing in everything. The lamp never "turns on" because it
| always was "on".
|
| As an electronics guy, the veritasium video just made my eyes
| roll.
