Definitions:

Total Current

The overall flow of electricity in a circuit, measured in amperes, which is constant throughout a series circuit.

Current Flow

The movement of electric charge carriers, such as electrons, through a conductor or circuit, typically directed from a positive to a negative point.

Applied Voltage

The voltage that is externally applied to an electrical device or circuit to initiate the flow of current.

R1

Often denoted as a variable for resistance in electrical equations and diagrams, representing a specific resistor's ohmic value.
