Salinometer

Salinometer

A salinometer is an instrument designed to measure the salinity , or dissolved salt content, of a solution . Since salinity affects both the electrical conductivity and the specific gravity of the solution , a salinometer will often have an EC meter or hydrometer and some means of converting those readings into salinity readings. A …

Aluminum Conductor

Aluminum Conductor

What is Aluminum Conductor: In physics and electrical engineering , a conductor is an object or type of material that allows the flow of charge ( electric current in one or more directions). Metallic materials are common electrical conductors. Electric current is generated by the flow of negatively charged electrons , positively charged holes and …

Electrical Power Distribution

Electrical Power Distribution

What is Electrical Power Distribution: Let us know about Electrical Power Distribution. The final step in electric power distribution is the distribution of electricity ; It carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and reduce the transmission voltage to medium voltage2 kV and With the use …

Difference Between Boiling Point and Melting Point

Difference Between Boiling Point and Melting Point

The main difference between boiling point and melting point is that boiling point is the temperature at which a liquid state changes to its gaseous state whereas melting point is the temperature at which a solid state changes to a liquid state . There are three states of matter: solid state, liquid state and gaseous state. If we change …

Eddy Current Sensor

Eddy Current Sensor

Eddy current sensor detect defects or distances to metal objects dynamically without contact, with precision, They are commonly employed to measure ferromagnetic and non-ferromagnetic substances. They are acceptable for applications in harsh industrial environments due to their exceptional tolerances, such as oil, dust, moisture and field interference. Flexible and miniature versions offered, which can also …

Relativistic Mass

Relativistic Mass

The term mass in special relativity has two meanings: invariant mass (also called rest mass) is an invariant quantity that is the same for all observers in all reference frames; Whereas relativistic mass depends on the velocity of the observer. According to the concept of mass-energy equivalence , invariant mass is equal to rest energy …

Relative Velocity

Relative Velocity

Relative velocity (also or ) is the velocity of an object or observer B in the rest frame of another object or observer A. Classical mechanics In one dimension (non-relativistic) We start with relativistic motion in the classical , (or non- relativistic , or Newtonian approximation ) that all motion is much less than the speed of light. This limit is associated …
