"Ohm's Law: Volts sqare/Watts = Ohms
or Volts/Amps = Ohms"
Yeah that is all good. But I want something that can tell me is the
block
heater working, ie drawing power and getting juice when it is 5 below
zero
F, the wind is blowing 30mph, my bag ass is frozen, no feelings in my
fingers, I have to get up at 1:00AM to drive 500 miles one way to Boston,
or
Chicago. Then I need to stay in a hotel, haul out my 100 foot extention
cord and do it all again and pray there is an outdoor outlet within 100
feet. So playing with lights in series, playing with electric meters at
home, or calculating things is just not as practical as a little $20
widget
you plug in in series and it tells you.
A) you got juice B) you are actually drawing power at the heater.
