Select scalar quantities from the following:
A. electric flux
B. Electric current
C. Current density
D. Electromagnetic force
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A, B and D only
(A) Electric flux $(\phi_E)=\vec E.\vec A$, Hence it is an scalar.
(B) Electric current (I) is also a scalar Quantity.
(D) EMF is a scalar quantity $(ε=-\frac{d\phi_E}{dt})$.
