In electrical theory and technician practice, understanding how charge carriers behave, how current is quantified, and how current is measured in a circuit is essential. Match each electrical current concept on the left with its correct fundamental characteristic or definition on the right.
- Electron flow directionThe physical drift of negatively charged particles from the negative terminal toward the positive terminal.
- Conventional current directionThe movement of charge modeled from the positive terminal toward the negative terminal of a source.
- One ampere ()The rate of electrical charge transfer equal to one coulomb passing through a cross-section per second ().
- Ammeter circuit placementA series configuration inserted directly into the conductive path so that the total stream of charge passes through the meter.
Answer
Electron flow direction matches the physical drift of negatively charged particles from negative to positive; Conventional current direction matches the model flowing from positive to negative; One ampere matches the transfer of one coulomb per second (); Ammeter circuit placement matches a series configuration inserted directly into the conductive path.
Each concept pairs with its precise physical and operational principle: electron flow tracks actual electron drift (negative to positive), conventional current tracks theoretical positive charge flow (positive to negative), the ampere is defined as coulombs per second, and current measurement requires a series ammeter connection.
