REWINDING FOR A CHANGE IN VOLTAGE Three-phase motors can also be rewound for a change in voltage. The only changes necessary are in the number of turns and the size of the wire. EXAMPLE: If a 220-volt motor is to be rewound to operate an 440 volts‚ use twice as many turns on each coil and one-half the circular-mil area of wire. In other words‚ if forty turns of No. 17 wire were used on the original motor‚ eighty turns of No. 20 should be used on the new motor. RECONNECTING THE POLYPHASE MOTOR

At this time‚ many people have been aware about advantages of nuclear power that can mitigate global warming impact but they don’t notice the disadvantages of nuclear power. The advantages of nuclear power are the emission of green house is relatively low‚ this technology is readily available‚ it can produce high amount of electrical energy. Whereas the disadvantage are the problem of radioactive waste‚ high risk‚ not renewable energy‚ not sustainable energy‚ etc. From the above explanation‚ nuclear

Consumers wanted a three hundred mile range and eighty-five mile per hour speed on their electric cars but this was not plausible when running off of a battery. a.ii. When customers compare cars they don’t care much about the environmental risks they only care about the price‚ the miles per gallon‚ and the mileage range. Customers had a difficult time seeing the difference between regular cars and electric cars so there was not enough demand. b. Battery Technology (not guilty) b.i. Batteries

Electric cars‚ although now commonly associated with the Tesla brand‚ have in actuality been around for more than 100 years and have since then risen and fallen in popularity and efficiency. The electric vehicle was created initially to replace the inefficient steam and gasoline-powered vehicles of the 20th century‚ however‚ as the years progressed and the dangers of global warming and greenhouse gas became more evident‚ the purpose of the electric car transitioned into providing a better alternative

Einstein). Electric cars are automobiles they use one or more electric motors‚ other than using more common gasoline powered engines. Electric cars use batteries; batteries are used to store energy. Since Electric motors don’t have to warm up they have instant torque‚ creating strong and smooth acceleration‚ which can give you a more satisfying ride. Electric cars are safer and better than gasoline powered cars‚ since they aren’t polluting the air as much as gas powered cars. Electric cars are high

Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The electrons move because of the battery voltage. The current flows in the opposing direction of the electrons and the electrons flow towards the positive
