What is vertical deflection plate?
As we mentioned earlier, a CRT can be used to graphically and visually plot an electronic signal,such as a sine wave. This is done by using a second set of deflection plates called VERTICAL-DEFLECTION PLATES
What types of material can a winding machine be used on?
A winding machine is used to wind the string, wire, cable, thread, rope, etc onto a spool or bobbin. They are of various types from simple winding machines to complex programmable winding machines like CNC winding machines. Mostly winding machines are used in textile, and paper industries, to quickly wrap a large amount of string or paper onto a spool. These winding machines are used by small to large businesses according to the winding needs.

In motor winding what is the difference between a lap winding and a wave winding?
When electricians and electrical engineers/repairmen are called upon to assess troubles in generators and motors, they often rewind different types of these machines. There are two families of armature (closed-circuit) windings: lap winding and wave winding, described by the commutator pitch used for winding. In mechanical terms, armature windings consist of coils connected to a commutator in Read more....direct-current machines; or coils are connected together in alternating-current machines to form groups or series.Lap winding, also called parallel or multiple winding, is the process of winding elements or coils lapping back when wound on armature cores. Lap circuits are connected in parallel between brushes. The front and back pitches are odd with opposite signs. Winding pitch equals the algebraic sum of the front and back pitches. The end of a coil is connected to the commutator and the start of the next coil under the same two poles. Single-lap windings always have the same number of current paths as field poles while double-lap windings have twice as many current paths as field poles. Triple-lap windings have three times the number of current paths as field poles.The zig-zag or wavy path of winding through slots of armatures defines single (two-circuit) wave windings and multiplex (series-parallel) windings. Half of the armature coils is connected in series and the other half is connected in parallel between brushes, no matter the number of poles. Winding pitch is equal to the sum of the front and back pitches, which both must be odd with the same sign. The end of a coil is joined to the armature and the beginning of another under the next two poles. A single-wave winding has two current paths between brush sets. The double-wave winding has four current paths between brush sets; and the triple-wave winding has six current paths.Wave winding is used mostly in small and medium sized machines (500-600 volts) for keeping the number of coils as small as possible. Applications requiring high voltages at low currents use wave windings while lap windings are used for lower voltage, higher current applications. Wave windings, for a given number of poles and armature conductors, give more emf (electric and magnetic fields) than lap windings.Examples of suitable symmetrical armature windings for DC-machines with different poles are: for two-pole machines, two-circuit lap winding is preferred over wave winding; for four-pole machines, two-circuit wave winding or four-circuit lap winding is suggested. Six-pole machines should use two-circuit wave or six-circuit lap winding since four-circuit wave winding is asymmetrical.
What is core type and sell type transformer?
Core transformer and shell transformer - it has a one window. - it has a two windows. - less mechanical protection - better mechanical protection to the coils. to the coils. -windings encircles the core. - core encircles the winding. - cylindrical windings are used. - sandwich type windings are used. - it is easy to repair. - it is not easy to repair.
Why electromagnetic deflection is used in tv-crt rather than electrostatic as in cro?
Electromagnetic deflection is used because it can create greater deflection angles of the electron beam compared to electrostatic deflection.
How do you use cosine?
cosine = adjacent/hypotenuse. It can be used as other trig functions can.
Why are sine and cosine functions used to describe periodic?
because sine & cosine functions are periodic.
How are Pancake Coils used in refrigeration?
Pancake Coils are often used as evaporator and condenser coils in refrigeration systems.
Which angle length does cosine give you?
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
Where to use sine and cosine in physics?
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
What is Magnetic Gun in Computer?
This refers to when electromagnets were used rather than electrostatics to direct electron flow in a CRT (Cathode Ray Tube). Coils would be placed around the neck of the tube to influence the deflection of the cathode ray (electron flow) to the screen.
