In basic electronics, distinguishing between charge behavior, measurement units, and current flow conventions is essential. Match each electrical concept on the left with its correct definition or governing rule on the right.
- Electron Flow TheoryThe actual physical movement of negative charge carriers drifting from the negative terminal toward the positive terminal
- Conventional Current TheoryThe flow of electrical charge assumed to travel from the positive terminal toward the negative terminal through an external circuit
- Electric Current ()The rate at which electric charge passes a specific point in a closed conducting path ()
- One Ampere ()The continuous transfer of one coulomb of electrical charge passing a cross-section per second ()
Cevap
Electron Flow Theory matches the movement of negative charge carriers from negative to positive; Conventional Current Theory matches the historical assumption of flow from positive to negative; Electric Current matches the rate of charge flow over time; One Ampere matches one coulomb of charge per second.
Each electrical term accurately maps to its standard scientific definition: Electron Flow describes negative electrons drifting toward the positive terminal; Conventional Current describes the standard positive-to-negative circuit model; Electric Current represents the rate of charge flow (); and One Ampere specifically equals one coulomb passing a given point in one second ().

Recall the fundamental dimensional relationships: Current is , so its unit () must be equal to . Then remember that because electrons possess a negative charge, like charges repel and opposite charges attract, forcing them to move away from the negative terminal toward the positive terminal.
