Mission EC1 Current - Question Group 2 Help
One ampere exists in a circuit when ____ flows by a certain point in a conductor in ____.
Definition of Electric Current:
Electric current is the rate at which charge flows past a point on a circuit. Mathematically, current is the quantity of charge that passes through a cross-sectional area on a circuit per unit of time.
Definition of the Ampere:
The standard metric unit of current is the ampere (abbreviated Amp or A). A current of 1.0 ampere is defined as the current that exists when 1.0 Coulomb of charge passes by a point on the circuit in 1.0 second.

The electric current (I) at a given point on a circuit is the quantity of charge (Q) that flows past that point per unit of time (t):
I = Q / t.
