One major disadvantage of a series circuit is that if one component fails, the entire circuit is broken, and none of the components works. This can lead to a complete failure of the electrical system.

A major disadvantage of a series circuit compared to a parallel circuit is its vulnerability to a single component failure. In a series circuit, if one element malfunctions or breaks, the entire circuit is interrupted, causing all connected devices to cease functioning. This lack of redundancy makes series circuits less reliable for applications where uninterrupted operation is crucial. In contrast, parallel circuits offer more robustness because each device has its own independent branch, ensuring that a failure in one component does not affect the operation of the others, making parallel circuits more reliable in practical applications.
