Why do moving coil dynamometer type instruments have quadratic scale?

bcs the torque developed in dynamometer instrument is directly proportional to the square of the current passes so thts why its scale is quadratic in nature


How do you check that the measuring equipment is within current calibration dates and that the instruments are correctly zeroed?

That depends on what type of measuring equipment.


What are the difference between absolute and secondary type of measuring instrument?

Absolute measuring instruments provide measurements based on a fixed reference point, such as zero, while secondary measuring instruments provide measurements based on a comparison to a known standard. Absolute instruments are generally more accurate and precise, but may be more costly and require calibration. Secondary instruments are typically less precise but can be more practical for everyday use.


What piece of equipment can measure a force?

A dynamometer is a type of equipment used to measure force, typically in units such as Newtons or pounds. It can be used for applications such as testing the strength of materials or measuring the force exerted by individuals during physical tasks.


What are the advantages and disadvantages of the VOM as compared to the electrical measuring instrument?

As a VOM (volt-ohm meter) is one type of electrical measuring instrument, it is unclear how to answer this question. It is almost as if you had asked "What are the advantages and disadvantages of the banana as compared to the edible plant part?"


What are the similarities of PMMC and moving iron type measuring instruments?

Both PMMC (Permanent Magnet Moving Coil) and moving iron type measuring instruments are analog devices used for measuring electrical quantities. They both operate based on the interaction between magnetic fields and electric currents to produce a mechanical deflection for display. Additionally, they are both commonly used in applications where accuracy and precision are important factors.


What instrument measures peak to peak voltage?

All Moving Iron Type measuring instruments major rms value of quantities.


Eddy current type dynamometer?

An Eddy Current absorption dynamometer produces braking torque using the principle of eddy currents induced in a rotating metallic disk, immersed in a magnetic field. It is basically an eddy current brake mounted in trunnion bearings. Its advantages are maintenance, control, simple construction and desirable speed-torque characteristics. The speed-torque characteristics make the eddy current dynamometer ideal for engine testing, and its versatility also allows effective use in testing transmissions, turbines, electric motors, gears, pumps and many other machines.


When measuring mass what type of instrument can be used?

A balance or scale is commonly used to measure mass accurately. These instruments provide a reading in units such as grams or kilograms.


Why scientist use tools such as thermometers and meter sticks when they make observation?

Scientists use measuring instruments whenever the can because everything cannot be observed by the senses so measuring instruments are needed instead.
