From the following pairs select the combination of right pairs from the given options:
(A) Angle : Radians
(B) Pressure : Volt
(C) Luminous intensity : Candela
(D) Work : Joule
(E) Power : Current
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A), (C) and (D) only
A pair is right only if the second word is the unit in which the first quantity is measured.
(A) Angle : Radians Correct. The radian is the SI unit of plane angle.
(B) Pressure : Volt Incorrect. Pressure is measured in pascal; the volt is the unit of electric potential difference.
(C) Luminous intensity : Candela Correct. The candela is the SI unit of luminous intensity, the brightness of a light source.
(D) Work : Joule Correct. Work and energy are measured in joules.
(E) Power : Current Incorrect. Current is a quantity, not a unit; power is measured in watts.
