Which of the following options is equal to one volt? (J = Joule, C = Coulomb, s = Second)
RRB Technicians Grade-III
2024
✓ Answer:D1 J/C
Voltage is energy per unit charge, so 1 V = 1 J/C.
32
The unit of force is
RRB NTPC
2021
✓ Answer:Bkg m s^-2
From F = ma, force has unit kg × m/s² = kg·m·s^-2.
33
SI unit of weight is
RRB JE; RRB Group D; RRB ALP & Technician
RRB JE; RRB Group D; RRB ALP & Technician
2019; 2018; 2018
✓ Answer:BNewton
Weight is a gravitational force, so its SI unit is newton.
34
Which of the following is the standard unit of energy in the international system of units (SI)?
RRB RPF SI
2024
✓ Answer:CJoule (J)
The SI unit of energy and work is the joule (J).
35
Which of the following is not a unit of temperature?
RRB Group D
2018
✓ Answer:BPascal
Fahrenheit, Celsius and kelvin are temperature scales; pascal is a unit of pressure.
36
Unit of momentum is
RRB ALP & Technician; RRB Group D; RRB Group D
RRB ALP & Technician; RRB Group D; RRB Group D
2018; 2018; 2018
✓ Answer:Bkg m s^-1
Momentum p = mv, so its SI unit is kg·m·s^-1.
37
What is the SI unit of luminous intensity?
RRB ALP (Stage-II); RRB RPF SI; RRB JE CBT-II
2025; 2024; 2019
✓ Answer:BCandela
Candela (cd) is one of the seven SI base units and measures luminous intensity.
38
The amount of radiation being emitted by a radioactive material is measured using the conventional unit
RRB NTPC
2021
✓ Answer:DCurie
Curie is a conventional unit of radioactivity. The SI unit is becquerel.
39
Unit of power in industry is
RRB ALP & Technician
RRB ALP & Technician
2018
✓ Answer:DHorsepower
Horsepower is a commonly used industrial unit of power; 1 hp is approximately 746 W.
40
How can Siemens, the derived unit for electrical conductance, be expressed in terms of SI base units?
RRB Technicians Grade-I
2024
✓ Answer:Akg^-1 m^-2 s^3 A^2
Conductance is the reciprocal of resistance. Since Ω = kg·m²·s^-3·A^-2, S = kg^-1·m^-2·s^3·A².
