Correct answer: electric current
Explanation:
Electric current is defined as the amount of charge passing through any cross-section of a conductor per unit time.
Mathematically: \[ I = \frac{Q}{t} \] where:
\( I \) = electric current (in amperes)
\( Q \) = charge (in coulombs)
\( t \) = time (in seconds)
Hence, the correct answer is: electric current.
