Electric (Kill-a-Watt) question
Today I used my kill-a-watt type energy meter to see how much electricity our washing machine needs for 1 cycle. When I hooked it up the washing machine was off, so I expected to see zeros, but that was not the case. It showed that the machine was pulling 0.033 ampers, but 0 watts. Here is more info:
Voltage between 231.4V and 233.4V Current 0.033A Frequency 50.10Hz Power 0W 7.9VA cos(phi) between 0.99 and 1.00 I know that W is usually not equal to VA, but is some function of VA and cos(phi). On the other hand, when the washing machine was spinning, cos(phi) was around 0.97 and W was almost equal to VA. My question is: Does my washing machine consume power when "off", ie. when the meter reads 0W but 0.033A and 7.9VA? |

I just hooked up my Kill-A-Watt to our washing machine. I watched the current for two minutes and saw only zeroes.
