P = power V = voltage I = current
P = V * I
V = I * R
P = I * I * R
Heat loss = I * I * R * time the circuit is on
For the same power, if we quadruple the voltage, we can cut the current by 75%. And this cuts the need for copper wire mass also by 75%.
Cutting the current to 1/4 of what it was…...
I just got a low-mileage, pre-driven Premium from my dealer. When I start up a window pops up asking for a 4-digit driver ID. This pin wasn’t forwarded by the previous owner, and the dealer has no idea how to get it. Not having it precludes syncing FordPass to the car, etc. I called the...
