What is called the winding around the CRT yoke that deflects the electron beam with its magnetic field?
It's called a deflection coil. If a c.r.t. uses magnetic deflection, there will be two deflection coils, a horizontal one and a vertical one.
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 is full scale deflection?
Full Scale Deflection is equal to the max value on a scale or meter. If a thermometer reads from -20 degrees to +100 degrees, the full scale deflection = 100 degrees and the range = 120 degrees
Is 25000 secant modulus better or worse than 120000 secant modulus?
that depends; if you are worried about deflection under load the higher the better to reduce deflection; but if you are worried about stress under temperature or constant input deflection, the lower the better.
Define the deflection sensitivity of CRT?
There is basically two cases: (It is recommended to read about Cathode Ray Tube Deflection prior to read this) 1 - Electrostatic Deflection: Is the voltage necessary to move the electronic beam by a unit of lenght. Usually is V/cm or V/in. Since there is no significant current flowing on the deflection plates, and these kind of CRTs (Cathode Ray Tubes) are using on measuring devices (on wich the lenght of the trace on the screen will be measured in a way or another), only the voltage is relevant on the specification of the CRT, and its effect on the moving of the bean. CRT manufacturers made a tremendous effort to make the relationship between the Voltage on the plates and the beam deflection to be linear. 2 - Magnetic Deflection: Used on most popular CRTs, as TVs, Monitors (now being replaced by LCDs). Is the product of the square of the total (Ap-p)current needed to deflect the beam tottaly on the screen (from left to right - horizontal deflection, or top to bottom - vertical deflection), and the inductance of the coil. It is understood as the minimum energy that the inductor (the deflection coil) must store to generate the magnetic field and move the beam totally on the screen. Magnetic is the most complicated deflection since there are several factor affecting the performance of the circuit, i.e. coil resistance, geometric limitations, core saturation, variation of core permeability. Is the product of the inductance of the coil by the peak-to-peak current, squared. Most of the time is given in mHApp^2, but less often found in OhmsApp^2 Needless to say that the CRT using this kind of deflection uses several types of correction of linearity, because now the beam does no move in a linear way with the surface of the screen. The most popular are East-West correction, Pin-Cushion correction, and S-correction.

Is horizontal deflection plate present in LCD?
no, its unnecessary.
Why time base circuit is used in a CRO?
It is used as the horizontal deflection voltage of the CRT.

What is horizontal deflection system in CRO?
in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically. For that purpose a horizontal deflection plate is provided in the cro. This deflection plate is supplied with voltages , so that the electrons passing through these plates get deflected horizontally.due to alternating voltages these electrons deflect right & left very quickly, that we humans fell it is a straight horizontal line due our perception. THE voltages is provided by sweep generator,which produce ramp voltages WHICH IS AMPLIFIED & PROVIDED TO HORIZONTAL DEFLECTION PLATES in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically.

What is horizontal and vertical amplifier in cathode ray oscilloscope?
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
What is difference between settlement and deflection?
Settlement refers to vertical movement of a structure's foundation or ground whereas deflection is the bending or curvature of a structural element like a beam or slab under load. Settlement is a downward movement while deflection is a lateral or horizontal displacement.
What is the deflection sensitivity of a cathode ray oscilloscope?
It is the deflection on the screen (meter) per volt of deflection

What is the clockwise deflection of air is the northern hemisphere and the counterclockwise deflection of air in the southern hemisphere?
The Coriolis effect is the clockwise deflection of air in the north hemisphere and the counterclockwise deflection in the Southern Hemisphere.
What is the clockwise deflection of air in the northern hemisphere and the and counterclockwise deflection of air in the southern hemisphere?
The Coriolis effect is the clockwise deflection of air in the north hemisphere and the counterclockwise deflection in the Southern Hemisphere.
How do you use deflection in a sentence?
The deflection of the ball caused it to change direction. The politician used deflection to redirect attention away from the controversial issue. The deflection of the light off the mirror created a dazzling effect in the room.
Why deflection magnetometer kept in tanA position?
A deflection magnetometer is kept in the tanA position to align the magnetic field produced by the Earth with the plane of the magnetometer's needle. This helps ensure accurate measurements of the horizontal component of the Earth's magnetic field by minimizing external disturbances. The tanA position helps in reducing errors in the measurement caused by stray magnetic fields or misalignment.
