T5A05
A difference in which of the following causes electron flow?
- A.Voltage (correct answer)
- B.Ampere-hours
- C.Capacitance
- D.Inductance
WhyA difference in voltage causes electron flow. A difference in voltage, electrical potential, between two points is what pushes electrons to flow between them, answer A. Ampere-hours (B) measure stored charge capacity, and capacitance (C) and inductance (D) describe a component's ability to store energy in electric and magnetic fields respectively, none of which is the driving force behind electron flow.
