tUsers of herot.com experienced a brief power outage today, occasioned by a brief rain shower punctuated by a loud pop as a tree branch fell on a power line.
NSTAR was on the scene in half an hour, and replaced a stretch of broken high voltage wire. I'm always impressed by how such a thin wire can supply power to an entire neighborhood. I=P/E which means for large values of E (voltage a.k.a. Electromotive Force) the amperage, I, is rather small and thus the wires don't need to be so large.
