What are elements that are made by fusing existing elements with fast moving particles?
Electroneoplytium
Do the elements go from metals to nonmetals or nonmetals to metals?
Moving from left to right on the periodic table, the elements generall go from metal to nonmetals.
Are cloudy days signs of a an earthquake?
No, they are signs that there is water vapor in the air. Earthquakes cannot be accurately forecast because there are very few signs ahead of time. One way scientists predict earthquakes is by measuring how much the ground around a fault is moving - they have to use special instruments that can measure the slow movements, though.
What are the functions of moving coil instrument?
The function of the moving coil is to deflect the instruments needle across a calibrated scale to give the meter operator an accurate reading of what ever he is testing. The moving coil is given a minute current, through internal instrument circuity, a sample of the potential that is being measured.
How does electricity relate to chemistry?
Electricity has a great relationship with chemistry. Electricity is produced by moving electrons pulled from the elements studied in chemistry.
What instrument measures peak to peak voltage?
All Moving Iron Type measuring instruments major rms value of quantities.
What is pmmc?
pmmc stands for permanent magnet moving coil instruments these instruments are secondary measuring instruments in these instruments a permanent magnet is installed and a moving coil in this way when current is passed through the fixed coil then a force will be developed on the moving coil and thus it moves and with this moving pointer moves on the scale and gives the corresponding reading . if someone wants to read it thoroughly then he can try ashfaq hussain , j.b.gupta of basic elelctrical engg. for b.tech first year .
When you are measuring temperature you are measuring the?
How fast molecules are moving. If they are moving fast its hot, but if they are moving slow it is cold
Is Voltmeter is a moving iron Instrument or moving coil instrument?
If this is a homework related question, you really should consider trying to solve it yourself before looking at this answer. Otherwise, the value of the lesson, and the reinforcement provided by the assignment, will be lost to you.A moving coil measuring instrument has a coil attached to the indicator, surrounded by a magnet.A moving iron measuring instrument has a magnet attached to the indicator, surrounded by a coil.In both cases, the indicator is driven by magnetic torque caused by current flow in the coil.
Why pmmc instrument measure only ac not dc?
Permanent magnet moving coil instruments are used for measuring d.c. quantities only. This is so because for these instruments the torque is proportional to the operating quantity either voltage or current.
What happens when a permanent magnet moving coil instrument be connected in an ac current?
The torque on the moving coil will reverse at twice the frequency of the supply, causing the pointer to vibrate. High-quality a.c. measuring instruments that incorporate a moving coil are, of course, common but incorporate a rectification circuit to supply the coil.
Instrument which does not have restoring torque?
moving iron instruments
Characteristics of erosion?
Moving of rocks
How do you find the speed of a moving object?
By measuring the distance and time
What are elements that are made by fusing existing elements with fast moving particles?
Electroneoplytium
Difference between equipment and instrument?
Equipments (also called as Tools) are the devices required to perform and/or expedite a task. There are various types of tools including cutting tools, moving tools, shaping tools, fastening tools, guiding & measuring tools. Instruments are the devices basically used to measure, record or identify any entity. It includes devices used in following sectors: electrical or electronic or scientific , medical, laboratory, vehicle, weather and measurement.
What characteristics is shared by elements in the same period?
Elements in the same period have the same number of electron shells, moving across a period (progressing group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
