To the Moon and Back

Updated: Mar 3, 2022

How long does it take to turn on a light if the switch, battery, and light are on the Earth, but the cable connecting them goes to the Moon and back? For anyone who is interested to understand the voltages and currents in circuit similar to the question about wires going to the moon, Steven Sandler has created a fantastic simulation.

Steve gets into variations with the source lighting, voltage vs. current impacts, and assessing the impedance and reflections with a TDR.

It's a short 15min video in response to the Eric Bogatin Blog on Veritasium Electricity and the Robert Feranec post.
