Question
Which statement(s) describe what is meant with voltage?
A.
It can be used to determine the amount of charge that flows through the circuit in the presence of a known resistance and if the circuit is closed
B.
It is a difference in charge between two points of an electrical circuit
C.
It is the driving force for electrical charge to flow through an electrical circuit
D.
It describes the amount of charge that flows through an electrical circuit
E.
It describes the electrical charge at a certain point of an electrical circuit
A.
It can be used to determine the amount of charge that flows through the circuit in the presence of a known resistance and if the circuit is closed
B.
It is a difference in charge between two points of an electrical circuit
C.
It is the driving force for electrical charge to flow through an electrical circuit
D.
It describes the amount of charge that flows through an electrical circuit
E.
It describes the electrical charge at a certain point of an electrical circuit
Explanation / Answer
A) V = IR , so if resistance is known Voltage can be used to determine current which is the amount of flow of charge.
B) Difference in charge between two points results in charge flow, but it is not related to Voltage.
C) The driving force for flow of charge is potential difference which is also called Voltage.
D) Amount of charge is not described by voltage
E) Electrical charge at a certain point is not at all related to voltage.
So the statements that describe Voltage are A & C.
