A) 48.8 mH
B) 200 mH
C) 290 mH
D) 320 mH
Correct Answer: D
Solution :
(d) 320 mH As \[\frac{{{L}_{1}}}{{{L}_{2}}}=\frac{N_{1}^{2}}{N_{2}^{2}}\] Here, self inductance of 500 turns coil =125 mH \[\therefore \] L for the coil of 800 turns \[=\frac{125}{{{(500)}^{2}}}\times {{(800)}^{2}}=320\,mH\]You need to login to perform this action.
