ELECTRICITY READINGS
Electric current consumption is shown in money by a small dial used in the United States, which shows the exact cost per hour for electricity to light lamps and operate electric appliances. The upper half of the dial is graduated in watts from 10 to 1400, and the lower half is graduated in cents and fractions of pennies. On the dial appear two arrows, opposite each other. To find the cost of operating a 60-watt lamp it is only necessary to turn the dial so one arrow points to 60. The opposite one then shows the cost per hour. On the back of the estimator is a table giving the average rating in watts of the various electrical appliances that are used in the home. The cost readings, of course, vary according to rates, hence such a dial must be made up according to the electricity rates charged for the locality in which it is to be used.
