[Boatanchors] More question on US AC voltage

[Brian A Clarke]

Another maths problem, Paul?
Though your Watt.hour meter is used to charge you, whenever you 
turn on an appliance, its resistance changes little. Consider an electric 
fire with a nominally 2 kW bar. Assume that the electricity distributor 
runs the voltage up 4% after everyone has finished cooking. If you 
turn this heater on when you get home from work and turn it off 
when you head for the pit, say, four hours later each evening, and 
say you pay 10c/kWhr, then you will have paid 45c/week more for 
power than you thought - OK?
Multiply this by the number of cold households your electricity 
distributor handles, and what have you?
On the supply side, the electricity distributor has to pay for the 
incoming suds at a combination of peak Volts and kWhr.
