What does the commutator do in an electric motor? On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils. What are the […]

What is the relation between electric field and distance?
What is the relation between electric field and distance? This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases. And by whatever factor the distance is changed, the electric field strength will change inversely by the square […]
What are the two mechanisms by which metal deforms?
What are the two mechanisms by which metal deforms? The mechanism by which metals deform is via the motion of linear defects at the atomistic scale, called dislocations (see the figure). In metals, dislocations are usually mobile, and their motion provides for the irreversible shifting of atomic planes in a process called slip, resulting in […]
Why should the number of classes in frequency distribution be between 5 and 20?
Why does my dryer cause so much static?
Why does my dryer cause so much static? The tumbling action of the dryer causes fabrics to rub against each other and build up the electrostatic charges that zap and cling. You’ve probably noticed that static cling is much worse in the winter than summer months. Static electricity is formed more easily when the air […]

Is infrared reflected by mirrors?
Is infrared reflected by mirrors? Do mirrors reflect only visible lights, or do they reflect light of other frequencies (if so then which types–x-ray, infrared, gamma, etc)? Yes and no, a normal mirror reflects visible light and likely near IR and UV, but it’s not optimized for anything past that. Do Humans give off infrared […]
