{"Image DocumentName": "34.11 Electric Powerthink!", "Image ImageDescription": "How much power is used by a calculator that operates on 8 volts and 0.1 ampere? If it is used for one hour, how much energy does it use? Answer: Power = current \u00d7 voltage = (0.1 A) \u00d7 (8 V) = 0.8 W. Energy = power \u00d7 time = (0.8 W) \u00d7 (1 h) = 0.8 watt-hour, or kilowatt-hour.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
