Dropped Neutral

[Steve L.]

Hi,

I was helping someone cut a tree down and it fell on the overhead triplex to the residence. The neutral wire was previously damaged and our branch severed it completely causing a T.V., flourescent light and a heating blanket to spark and burn out. I spoke with the power co. worker but did not fully understand his explanation. Can you help?

All those loads became series loads on a 240 volt circuit and the higher resistance loads saw an elevation in voltage I x R = V

Using the above formula calculate the voltages on each of the lamps in the open neutral circuit below

180V and 60V ,respectively. The OP has YEARS and YEARS more experience in the field than me...Do I get a cookie?
