Total Inductance vs Inductor L1
公式
## Series Inductors **L_total = L1 + L2 + L3 + ...** Inductances add directly in series, just like resistors in series. Assumes no mutual coupling.
计算示例
10 mH and 22 mH in series.
- 01L_total = 10 + 22 = 32 mH
常见问题
Do series inductors always add?
Yes, assuming no magnetic coupling. With coupling, mutual inductance adds or subtracts depending on orientation.
Why series instead of one larger inductor?
To achieve non-standard values or distribute heat across components.
Current through series inductors?
Same current flows through all, just like series resistors.
