★Fourier series makes it easier to analyze linear constant-coefficient differential equations. like every RCL plus amplifier circuit. Any series expansion in terms of natural solutions to a differential equation, which may also be used to analyze the forcing function of the system would work, but in this case, complex exponentials are extraordinarily useful.
★Periodic signals are the shame and teaching hack of this particular set of mathematical tools. Fourier series/transforms have wider applicability than that. But that's a different problem and question.

Step-by-step explanation:
Fourier series makes it easier to represent periodic signals as it is a mathematical tool that allows the representation of any periodic signals as the sum of harmonically related sinusoids.
