Definitions:

Return Path

The return path is the conductive path that allows current to return to its source in an electrical circuit, completing the circuit loop.

Voltage Drop

The reduction in voltage as electric current passes through components or conductive paths within an electrical circuit, due to resistance or impedance.

Total Resistance

The overall opposition to electric current flow in a circuit, calculated by adding the resistance values of individual resistors in series and appropriately combining resistors in parallel.

Parallel Circuit

An electrical circuit in which components are connected in parallel, such that the voltage across each component is the same, and the total current is the sum of the currents through each component.
