Definitions:

Parallel

An electrical circuit configuration where components are connected across the same two points, providing multiple paths for the current.

Series

A circuit configuration where components are connected in a linear sequence so that the same current flows through each component.

Two-Branch

Refers to a circuit configuration that splits into two distinct paths or branches, often used in parallel circuit analysis.

Parallel Circuit

A circuit in which components are connected across common points or junctions, providing multiple paths for current flow.
