Doc uses an unfinished model of Hill Valley’s Courthouse Square to explain how he’s going to send Marty back to 1985.

One thought on “BTTF Minute 70 – The Exposition Scene

  1. So I’m definitely not an electrical engineer, but the total power running through a line isn’t reduced by running side outlets to draw off excess power, but rather using a device or medium that creates resistance. The length, width and material type of a cable will having varying levels of resistance, while transformers or regulators are devices that can control power output.

    I’m guessing Doc would have used equipment to help give him an ideal amount of power output needed for the DeLorean based on his expectation for how much power the lightning would create.
