Definitions:

Voltage Divider

A circuit that generally is constructed by connecting resistors in series to produce desired voltage drops across the resistors.

Voltages

The electrical potential difference between two points in a circuit, measured in volts (V), driving current flow through the circuit.

Total Resistance

The overall resistance in an electrical circuit, calculated differently for series and parallel circuits.

Applied Voltage

Applied voltage refers to the electrical potential difference intentionally established across a component or circuit for operation.
