Why pmmc used for DC only?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.
Is Series resistance and PMMC used as voltmeter?
yes
When are micrometers used?
When you need very tiny measurements.
How are measurements used in construction?
The construction field use scales as measurements for the exact calculation of distance and deepness in every materials. The measurements are use to create a well calibrate construction who will stand the test of time.
Is a ammeter a resistor?
Usually, but some voltmeters are limited in the range of resistances they can measure.AnswerNo, voltmeters measure voltage, notresistance.
Why pmmc used for DC only?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.
Is Series resistance and PMMC used as voltmeter?
yes
Why PM MC meters can't be used for AC measurements?
It wont work for AC measurements. Not designed for AC application
When at kilometers used?
Kilometers are used for long distance measurements and 1000 meters = 1 kilometer
How do you convert from grams to meter?
you can't convert grams to meters. Grams are used to measure weight and meters are used to measure distance.They are both metric measurements but they measure different things.
Why pmmc instrument is cannot be used to measure ac?
Pmmc meter are most accurate instrument for DC measurement however they are unable to measure the AC quantity. The working principle is as follows: a moving coil is free to move in a external static magnetic field. And the pointer moves according to the interaction of two fields, field of static mag. and that of measuring quantity. Now in case of it is impossible to produce a sustained magnetic field, that's why we can not use PMMC to measure the ac.
How is geomerty used in the real world?
without geometry, we cant build a house in a right manner because, we need to now the angles and the right measurements....
What are 2 advantages of used SI measurements?
SI measurements are used everywhere.It makes study of measurements easier.
What is a sewing ruler?
A ruler is used to measure things. The most common measurements used of rulers are centimeters, millimeter's, meters and inches. You use it in sewing to measure the length of what you are sewing together.
What would you measure with a decimeter?
Decimeter unit length in the metric system. 1 decimeter is equal to 0.1 meters. Decimeter is used less in length measurements.
Are measurements data?
Yes, measurements are data, as they can be used and manipulated, in order to be presented, or used for further research
Why are soccer field dimensions in yards instead of meters. For example the 18 yard penalty box.?
Prior to the widespread implementation of the metric system, imperial measurements, such as inches, feet, yards, and miles, were used. This measurement system is still used predominantly in the United States and other countries, though most now rely upon the metric system (millimeters, centimeters, meters, kilometers, and so on). At the time the Laws of the Game were established, the imperial system was used in England, where the Laws were first written. Although the Laws now indicate metric measurements, the imperial measurements are kept as a matter of tradition.
