MCQ
The dimensions of $emf$ in $MKS$ is
- A$M{L^{ - 1}}{T^{ - 2}}{Q^{ - 2}}$
- B$M{L^2}{T^{ - 2}}{Q^{ - 2}}$
- C$ML{T^{ - 2}}{Q^{ - 1}}$
- ✓$M{L^2}{T^{ - 2}}{Q^{ - 1}}$
✓
Answer
Correct option: D.
$M{L^2}{T^{ - 2}}{Q^{ - 1}}$
d
(d) $e = L\frac{{di}}{{dt}} \Rightarrow [e] = [M{L^2}{T^{ - 2}}{A^{ - 2}}]\,\left[ {\frac{A}{T}} \right]$
(d) $e = L\frac{{di}}{{dt}} \Rightarrow [e] = [M{L^2}{T^{ - 2}}{A^{ - 2}}]\,\left[ {\frac{A}{T}} \right]$
$[e] = \left[ {\frac{{M{L^2}{T^{ - 2}}}}{{AT}}} \right] = [M{L^2}{T^{ - 2}}{Q^{ - 1}}]$
