How is the total inductance calculated in a series circuit?

In a series circuit, the total inductance is calculated by summing the individual inductances of each inductor connected in series. This relationship arises because the magnetic fields created by each inductor add together, leading to a combined inductance that is reflective of all inductors' contributions to the overall circuit. Therefore, the formula used to find the total inductance is simply the sum of all inductances involved, which can be expressed as L_total = L1 + L2 + L3 + ..., where L1, L2, L3, etc., represent the inductances of each inductor in the series.

This approach to calculating inductance contrasts with other circuit configurations and mathematical operations that do not pertain to series inductors. For example, multiplying inductances is relevant in specific contexts, such as calculating equivalent inductance in parallel circuits but does not apply to series connections. Subtracting values does not represent any physical relationship in inductance, and dividing inductances does not yield a meaningful total inductance either. Understanding the proper method for calculating total inductance is crucial for effectively analyzing and designing circuits.
