You can work out exactly how much power it draws from you electric meter.
Most meters are 66.6 revs per KWhour or 133.3 revs / KWhr.
(It will be written somewhere on the meter face in small letters.)
So,... to work out the power draw on your new 180 inch Plasma tv;
turn off fridge and airconditioner, and anything else that might cycle on and off during test.
Check power meter and time exactly how long 1 rev of the wheel takes. (say it's 45 seconds)
Therefore power draw with tv off is 3600 / 45 / 66.6 = 1.2KWatts
Turn on 180 inch plasma tv. and repeat meter wheel spin time, say it's now 36 sec.
new power draw is 3600 / 36 / 66.6 = 1.5KW,
Subtract the first from the last,
which means tv draws 1.5 minus 1.2 KW = .3Kw or 300 watts.
Which means if it's on for 5 hours a night it's still only 5 X 300 = 3KWhour.
Which is only 3 X 12.7 cents = 38 cents!
7 days a week = $2.66
Cheap at twice the price. You need a bigger tv !
(don't forget to turn the fridge back on!)
