Question:
Two inductors \( L_1 \) and \( L_2 \) are connected such that their fluxes are in opposite directions. The total inductance \( L \) will be:
Two inductors \( L_1 \) and \( L_2 \) are connected such that their fluxes are in opposite directions. The total inductance \( L \) will be:
Show Hint
If inductors aid each other, use \( +2M \). If they oppose each other, use \( -2M \).
Updated On: Mar 26, 2025
- \( L = L_1 + L_2 + M \)
- \( L = L_1 + L_2 + 2M \)
- \( L = L_1 + L_2 - 2M \)
- \( L = L_1 + L_2 - M \)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
When two inductors are connected in series but their fluxes oppose each other, the total inductance is:
\[
L = L_1 + L_2 - 2M
\]
where \( M \) is the mutual inductance.
