Question 1 Report
Which of the following is a derived unit?
A derived unit is a unit of measurement that is derived from the seven base units of the International System of Units (SI). The base units are the units for length, mass, time, electric current, temperature, amount of substance, and luminous intensity. The units of metre, kilogram, second and ampere are base units, whereas the unit of coulomb is a derived unit, defined as the quantity of electric charge transported by a constant current of one ampere in one second. Therefore, the correct answer is Coulomb.
