How is the left-hand rule related to current and magnetic field?
It is related to the flow of electrons in a conductor through aseparate magnetic field. If you point your index finger straight place your thumb up and place your middle finger at a 90 degree angle to the other two (unless you are really double jointed there is only one way to do it.). The direction of current and your wire is the middle finger the direction of magnetic plane pointing north is your index finger and the direction of force is your thumb. There is also the right hand rule. If you look at your right hand with your thumb up and fingers curved, If you held a piece of wire in your hand with the current traveling along the direction of your thumb the magnetic field would rotate in the direction of your fingers.
Sinusoidal pwm generation using modulation index?
Not sure what type of modulation you are looking for, but there are two that can be manipulated, either individually or in conjunction:Frequency modulation index refers to the relation between the sine wave frequency (sine_freq) and the triangle (or saw-tooth) wave frequency (triang_freq).The frequency modulation index is equal to ((triang_freq)/(sine_freq)).Amplitude modulation index refers to the relation between the sine wave amplitude (sine_amp) and the triangle (or saw-tooth) wave amplitude (triang_amp).The amplitude modulation index is equal to ((sine_amp)/(triang_amp)).Varying the modulation index (normally by varying the frequency or amplitude of the triangle wave form) changes that respective modulation index.From personal experience, an appropriate amplitude modulation index for an SPWM waveform should be around 0.8(that is, if the triangle has an amplitude of 10, the sine would have an amplitude of 8). This index should never be equal to 1 (one); it should always be less. A.K.A.: the triangle-wave amplitude should always be greater than the sine-wave.On the other hand, a triangle-wave frequency much greaterthan the sine-wave frequency makes an SPWM that in turn generates a "cleaner" synthesized sine-wave in the H-bridge you are probably using. Try different freq. modulation indexes, but an index of at least 10 should be used (preferably somewhere around 100 if you want a good SPWM). That is, if the sine-wave frequency is 60 Hz, the triangle-wave frequency should be above 600, preferably 6,000 or more. Complications in the filter design in the "output" of the H-bridge will vary greatly when playing around with the frequency modulation index. That being said, keeping the amplitude modulation index at a static 0.8, and playing around with the triangle-wave frequency should be your best bet.
What does the new index property return?
The new index property return the selected item number of a list box. Say their is a list box of 1 item the index is 0. You can get the index by one line of code. Listbox1.SelectedIndex.ToString That's all the index does.
What is no follow in web design and webpages?
In web page design, the author can specify whether the Bots should or should not follow and index all pages and links. The command is one known as a META and is placed in the HEAD section of the webpage. For "follow", the syntax of the command is: an opening bracket meta name="robots" content="index,follow" then a closing bracket For "follow", the syntax of the command is: an opening bracket meta name="robots" content="index,no-follow" then a closing bracket
What do you think is a carrier's maximum modulation index without over-modulation?
The maximum modulation index for a carrier signal without resulting in over-modulation typically depends on the modulation scheme being used. For standard amplitude modulation (AM), the maximum modulation index is generally 1, meaning the peak envelope power of the modulated signal should not exceed the carrier power. In frequency modulation (FM), the modulation index can be higher, but it should still be kept within limits defined by the system to avoid distortion. Ultimately, the precise value can vary based on specific application requirements and the desired quality of the transmitted signal.
What is the collective noun for index?
The noun index is a word for an alphabetical list. The noun index can itself be a collective noun for an index of subjects, an index of titles, an index of keywords, etc.
What are ideal requisites of an dental index?
ideally, an index should possess the following properties:clarity, simplicity and objectivity:-the index should be easy to apply so that there is no undue time lost during field examination. the criteria of the index should be clear and unambiguous.validity:- it must measure what it is intended to measure, so it should correspond to clinical stages of the disease under study at each pointreliability:- the index should measure consistently at different times and a variety of conditions. the ability of the same or different to interpret and use the index in the same wayquantifiability:- it should be responsive to the statistical analysis so that the status can be expressed by a number that corresponds to a relative position on a scale of 0 to the upper limitsensitivity:- should be able to detect reasonably small shifts in either direction in the group or individual conditions.acceptability:- the use od index should not be painful or demeaning to the subject.
What is the meaning of index of a book?
The index is always in the front of a book, it shows which chapters and what page it is on.
What is CLD in masm?
Clear direction flag (CLD) means that index registers will be incremented when looping through a string. Opposite of STD (set direction flag), which means the index registers of the string will be decremented when looping.
What indicates how much a medium can change the direction of light?
It is indicated by the refractive index of the medium.
Should gomed be worn in index finger of right hand?
can gomad be worn in index finger
Your index number can not be found please help me out?
Why should I help you?! It's my index number that cannot be found!
Does oil has the same refractive index as glass?
No, oil does not have the same refractive index as glass. Glass typically has a higher refractive index than most oils. This difference in refractive index is what causes light to bend or change direction when it passes from one medium (like oil) to another (like glass).
What is the meaning of index htm?
Each web server has a directory. Index htm or index html is the default page name in that directory. The main page or homepage should have the extension index htm.
What should I know about money before investing in an index fund?
An index fund tries to replicate a "market index", that is, the aggregate movements of a segment of the market. The most important thing to know about an index fund is that the fund will attempt to mirror the index, EVEN IF the index is moving downward, losing you money. You should always be arare of any potential risk to loose your investment. Investing in an index fund is a relativley safe investment,but there is always risk.
Is refractive index scalar or vector?
Refractive index is a scalar quantity because it describes how light propagates through a medium by bending, or refracting, without considering a specific direction of travel.
What are graphic index and motion vectors in continuity editing?
graphic vectors- created by lines on screen to lead the eye in a general direction index vectors- points unquestionably in a direction. like an actor's pointing hand or a neon arrow motion vector- uses an object in motion to draw the eye
