peter	Re: Caps as heater droppers Actually you wouldn't be consuming the 1400W, because the voltage and current would be nearly 90 degrees out of phase. Your electric meter by which they bill you for power responds to the actual power consumed, and doesn't measure this. However, the power company isn;t very happy about it because they still have to pay for the resistive losses in the wires leading up to your house, which will be the same regardless of the phase angle. As a result, if you have for example a factory which uses lots of inductive loads like big motors, they measure the phase angle (which gets renamed 'power factor') and bill you accordingly! bet that's more than you wanted to know!
