Dynamo A device that converts mechanical power into electrical power with a direct current. Eddy Currents Small closed loops of current within a conductor or magnet. In a transformer these currents act against the magnetic flux that generates a current in the secondary coil, making the transformer less efficient and heating the core. Electrical Conductance The inverse of resistance. A measure of how well an object conducts electricity. Electromagnetic Induction When a current carrying...

What is the name of the invisible force that is created around the wire when electrons flow through a wire? Magnetic field What is electromagnetism? The creation of a magnetic field by the flow of electric current is referred to as electromagnetism. What does winding the conductor into a coil cause? Winding the conductor into a coil causes the magnetic field to become stronger. The ____________ of the field increases as the number of windings (turns) increases. Strength ...

1d collisions head on collisions sticking together ANSWER : mv - mv = collective mass x v 1d collisions in the same direction not sticking together ANSWER : mv + mv = mv + mv 1d collisions in the same direction sticking together ANSWER : mv + mv = collective mass x v 1d explosions ANSWER : mv + 0 = collective mass x v 1d recoil ANSWER : 0 = mv + mv Gun velocity will be negative as it is going back 2d collisions ANSWER : Total momentum in vertical component Total momentum in ho...

Engine Electrical Final Exam Practice Test. What device is used to convert alternating current, which has been induced into the loops of the rotating armature of a dc generator, to direct current? - CORRECT ANSWER A commutator. A certain direct current series motor mounted within an aircraft draws more amperes during start than when it is running under its rated load. The most logical conclusion that may be drawn is - CORRECT ANSWER the condition is normal for this type of motor. The ...
