An ampere is the amount of electric current existing when _______ flows past a point on a circuit in one second.

Question

An ampere is the amount of electric current existing when _______ flows past a point on a circuit in one second.?  
A. volt  
B. ohm  
C. coulomb  
D. watt

Accepted Answer

Correct Answer: (C)coulomb. 
Rationale: An ampere is the amount of electric current existing when one coulomb of charge flows past a point in a circuit in one second.Electric current measures the rate at which electric charge moves through a conductor. By definition, current is the amount of charge passing a given point per unit time. The SI unit of charge is the coulomb, and the SI unit of current is the ampere. Their relationship is expressed as:one ampere equals one coulomb per second.A) voltA volt is the unit of electric potential difference. It describes how much energy per unit charge is available to move charges through a circuit, not how much charge actually flows past a point.B) ohmAn ohm is the unit of electrical resistance. It indicates how much a material opposes the flow of current but does not measure charge or current itself.C) coulombA coulomb is the unit of electric charge. When one coulomb of charge passes a point in a circuit every second, the current at that point is one ampere. This directly matches the formal definition of electric current.D) wattA watt is the unit of power, representing the rate at which energy is transferred or used (joules per second). It does not measure electric charge or current directly.ConclusionElectric current is defined as the flow of electric charge per unit time. Since one ampere equals one coulomb passing a point each second, the correct completion of the statement is coulomb.
