A) 90V
B) 120V
C) 220V
D) 30V
Correct Answer: B
Solution :
The magnetic flux linked with the primary coil is given by \[\lambda \] So, voltage across primary \[{{\left( \frac{1}{2} \right)}^{2}}\] = 4V (as \[\frac{1}{4\lambda }\]= constant) Also, we have \[4\lambda \] and \[2\lambda \] From relation, \[\frac{1}{2\lambda }\] or \[\frac{qvR}{2}\] \[qv{{R}^{2}}\]You need to login to perform this action.
