Which system has been accepted as the international standards of measurement with seven base units for length, mass, time, temperature, electric current, luminous intensity and amount of substance? I. Metric system II. Imperial or British system

Which system has been accepted as the international standards of measurement with seven base units for length, mass, time, temperature, electric current, luminous intensity and amount of substance? I. Metric system II. Imperial or British system Correct Answer Only I

An international system of units, called SI units, was adopted at the 11th General Conference on Weights and Measures (CGPM) in 1960. SI is an abbreviation of the French name “Le Systeme Internationale de Unite’s”.

Currently, we follow an international system of units, called SI units. This system is based on seven base units which correspond to seven base physical quantities namely length, mass, time, temperature, amount of substances, light intensity and electric current.

Base Physical Quantity Symbol of Physical Quantity Name of SI Unit Symbol of SI Unit
length l metre m
mass m kilogram kg
time t second s
electric current I ampere A
thermodynamic temperature T kelvin K
amount of substance n mole mol
luminous intensity I candela cd

 

Hence, we conclude that the above statement is about the metric system.

When an electric current coil of a wattmeter is connected to the electric current path R and the voltage coil is connected between the electric current R path and the neutral side of the balanced three phase supply, it shows 10 kW. The line voltage along the phase sequence RYB is 400 V. The current drawn by the current path is 54 A. What is the new reading of the wattmeter if the voltage coil is connected between the lines B and the Y paths, even if the electric current coil is continuously present in the line R?
