What is a Series Circuit?
A Series Circuit is a type of electrical configuration where all components are connected along a single path, so the same current flows through each component sequentially. This means if one component fails or is disconnected, the entire circuit stops working. Series circuits are commonly found in simple applications like old-fashioned Christmas lights or basic electrical experiments.
In residential and commercial electrical work, series circuits are typically avoided for critical systems because they lack redundancy. However, they are still used in specific low-power setups where current consistency is needed. For instance, a thermostat might use a series circuit for temperature-sensing elements. Electricians must carefully plan circuit designs to ensure that the loss of a single device doesn’t interrupt power to others unless intentional.
