Series versus parallel circuits pic

What is the difference between a series and parallel circuit?

Ultimately, the difference between a series and parallel circuit can be summarized in the following two sentences. In a series circuit, components are connected from end to end, creating a single path for current to flow. All elements within the circuit have the same current running through them.

What is a parallel circuit?

In a parallel circuit, all components are connected, sharing two electrical nodes. Each component has the same voltage across it. Of course, most circuits nowadays are neither purely series nor purely parallel, but a mix of both. Oftentimes, you will see subcircuits within a larger circuit that contain parallel elements or series elements.

What is a series-parallel circuit?

Usually, we find circuits where more than two components are connected together. There are two fundamental ways in which to connect more than two circuit components: series and parallel. These two basic connection methods can be combined to create more complex series-parallel circuits.

Why are series and parallel circuits important?

Series and parallel circuits are the building blocks of electronics. Understanding their behavior and applications enables engineers and hobbyists to design reliable and efficient systems. Series circuits guarantee a uniform flow of current, however, their limited one-path topology makes them prone to failures.
