(i) henry |
(ii) \[\frac{\text{volt - second}}{\text{ampere}}\] |
(iii) \[\frac{\text{volt }}{\text{ampere}}\] |
(iv) \[\frac{\text{joule }}{\text{amper}{{\text{e}}^{2}}}\] |
The correct statements are |
A) (i), (ii) and (iii)
B) (i), (ii) and (iv)
C) (iii) and (iv)
D) (ii) and (iii)
Correct Answer: B
Solution :
[b] Time constant in \[C-R\]and \[L-R\] circuits are CR and\[\frac{L}{R}\]respectively. Hence \[CR\equiv L\] or \[C{{R}^{2}}\equiv L\] i.e., units of \[C{{R}^{2}}\] and L are same. Now \[|e|=L\left( \frac{di}{dt} \right)\] and \[U=\frac{1}{2}L{{i}^{2}}\] Therefore, units of L or \[C{{R}^{2}}\] are Henry, \[\frac{volt-\sec ond}{ampere}\] and\[joule/amper{{e}^{2}}.\]You need to login to perform this action.
