Which of the following physical quantities is a scalar quantity?
A. Electric current✓ Correct Answer
B. Magnetic field intensity
C. Linear momentum
D. Torque
💡 Solution & Explanation
Electric current is classified as a scalar quantity because it possesses both magnitude and direction yet fails to obey vector addition laws. Vector quantities like torque, linear momentum, and magnetic fields strictly require vector addition rules during compounding. Scalar quantities in physics are fully specified by magnitude and appropriate units alone.
