Detailed Explanation of Inductance Formulas

When multiple inductors are connected in series, the total inductance is the sum of the individual inductances, assuming no mutual coupling. This is expressed as:

$L_{\text{total}} = \sum_{i=1}^{n} L_i$

where $L_i$ is the inductance of each inductor in henrys (H).

For parallel connections, the total inductance is found using the reciprocal formula:

$\frac{1}{L_{\text{total}}} = \sum_{i=1}^{n} \frac{1}{L_i}$

which can be rearranged to $L_{\text{total}} = \left( \sum_{i=1}^{n} \frac{1}{L_i} \right)^{-1}$. These relationships are crucial for circuit design but may vary if mutual inductance is present, requiring adjustments for practical applications.
