PPT-Electric Power

Lesson 25 Key Concepts How do you calculate electric power What factors are used to determine how people pay for electrical energy Energy Transformation An electric appliance transforms electrical energy into another form. An . electric bicycle. , also known as an . e-bike.  or . booster bike. , is a bicycle with an integrated electric motor which can be used for propulsion. . There is a great variety of e-bikes available worldwide, from e-bikes that only have a small motor to assist the rider's pedal-power to somewhat more powerful e-bikes which tend closer to moped-style functionality.. Electric Power. . is the rate at which energy . converted or . is used. .. The . watt . (W) is a unit of power. . Since energy is measured in . joules. , power is measured in joules per second. . One joule per second is equal to one watt.. The "jet" or exhaust power (P. jet. ) of any thruster is: . P. jet. = 1/2 g. c. I. sp. F . Thus, for a situation where we wish to fix the thrust at a constant value, as specific impulse increases, the jet power must also increase. . Electric . Power, AC, and DC Electricity. Key Question:. How much does electricity cost and what do you pay for?. *Students read Section 20.3 AFTER Investigation 20.3. Electric . Power, AC, and DC Electricity. Scott Norr, P.E.. EE 4501. September 20, 2016. Electric Power Delivery and Consumption Getting More Complex. More Environmental Issues - . SUSTAINABILITY. Greater Population Density. Larger Variety of Sources, Delivery Methods and Loads. Electric current. . is the rate of electron flow past a specific point in the circuit (how . fast . electrons pass . through a . point in the wire).. The symbol for electric current is . I. ..

For centuries, humans have used falling water to provide power for grain and saw mills, as well as other activities.. The 1. st. use of moving water to produce electricity was a waterwheel on the Fox River in Wisconsin in 1882, two years after Thomas Edison created the incandescent light bulb..
