WHAT ARE YOUR OPERATING COSTS?

HOW TO CHECK THEM. It is easy to check the current con--umod by an electric- set and. compare It with the average electric light lamp, by noting how fast the metal disk revolves on the wati-hour meter. For mstunce, with all current in the house turned off the disk ..should not move at all. If with a 75-watt lamp turned on the disk revolves five times in one min•ites, and with only the radio set turned on it revolves fifteen times in one minute, it is obvious that ihe radio consumes three times as much power as the 75-watt lamp, or 225 watts. Multiply this by the number of hours a month the r;ct is in operation, divide by one thousand and multiply by jthe cost of. your clcctii/dty a kilowatt, hour ■(refer- to your bilijv and you will know what it costs for current to operate your radio for one month. This will invariably be less vhan the cost of charging batteries' and buying new 'B* batteries, according to George Lewis, noted tube expert.
