Which of the following is a derived unit? A.Ampere B.Kilogramme C.Second D.Ohm E.Kelvin
Question
Which of the following is a derived unit? A.Ampere B.Kilogramme C.Second D.Ohm E.Kelvin
Solution
The derived unit from the options provided is D. Ohm.
Here's why:
A derived unit in the International System of Units (SI) is a unit of measurement that is defined by a combination of base units.
A. Ampere is a base unit for electric current. B. Kilogramme is a base unit for mass. C. Second is a base unit for time. E. Kelvin is a base unit for temperature.
D. Ohm, however, is a derived unit. It is used to measure electrical resistance and its SI unit is kg⋅m²⋅s⁻³⋅A⁻² (kilogram meter squared per second cubed per ampere squared). This is derived from the base units mentioned above.
