Question

Difficulty: EasyElectrical Current and Electron Flow

In electrical circuits, an electric current of one ampere (1 A1\text{ A}) is defined as one coulomb of electrical charge passing through a given point in one second.

Answer: Answer

Answer

True
Electric current is the measure of how much electrical charge flows past a specific point per unit of time. Under the International System of Units (SI), a current of one ampere is exactly one coulomb of charge traveling past a reference plane per second.

Step-by-Step Solution

1
Identify the standard formula relating electric current, electrical charge, and time.
The formula is I=QtI = \frac{Q}{t}, where II is current, QQ is charge in coulombs, and tt is time in seconds.
Current quantifies the rate of electrical charge movement across a conductor cross-section.
2
Substitute standard SI base units into the rate equation.
1 Ampere=1 Coulomb1 Second1\text{ Ampere} = \frac{1\text{ Coulomb}}{1\text{ Second}} (1 A=1 C/s1\text{ A} = 1\text{ C/s}).
This establishes that one ampere directly equals one coulomb per second.

Key Concept

Definition of electric current as the rate of electrical charge flow in coulombs per second (1 A=1 C/s1\text{ A} = 1\text{ C/s}).
