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...

NCATT (AET) Latest Update Graded A Ampere ( A, amp, amperage) • Unit of measurement used to express the flow of electrons (electrical current) • One ampere is a rate of flow of one coulomb (6.28 billion - billion electrons) passing a given point in an electrical circuit per second • In mathematical problems amperage is expressed by the letter "I" Battery • A device consisting of a number of primary voltaic cells (cells that cannot be recharged) or secondary cells (cells that can be re...

Fracture is a type of material failure. Of the following which is another type of material failure? - Permanent deformation. Which of the following statements best differentiates between a defect and a discontinuity? - Discontinuities can propagate and become defects. Nondestructive testing is often differentiated from other measurements or inspection techniques in that: - NDT involves indirect tests related to some other quality or characteristic of material. What are the functions of ...

PHYS 222 EXAM 1 OPENSTAX - Q & A If you place a compass in a magnetic field, in what direction would the north end of the compass needle point? In the positive direction of the field An iron ring is magnetized by placing it near the north pole of a bar magnet. How would the magnetic field lines of the iron ring appear once it is magnetized? Vertical lines arrow in, perpendicular to the right What is the direction of the magnetic field at the poles of a bar magnet? It points inward at the South...
