X: Flow of electrons
Y: High potential energy
Z: Low potential energy
Potential difference is measured in units called ___________.
.
Volts
Why is copper used for most electrical wiring?
It is a good conductor.
Measurements of two electric currents are shown in the chart.
Which best compares the two currents?
Current Y has a greater potential difference, and the charges flow at a slower rate.
Which lists types of materials from most conductive to least conductive?
NOT
insulator,
semiconductor,
conductor,
superconductor
In the diagram, the arrow shows the movement of electric charges through a wire connected to a battery.
What causes the electric charges to flow from one end of the battery to the other?
a difference in electric potential
Which most likely has the greatest conductivity?
a cool lead metal strip
Jodi made a list about electric current to help her study for a test.
1) Movement of electrons is continuous in a current.
2) Electrons move from areas of low to high electric potential.
3) Voltage causes current to flow.
4) Rate at which current flows is measured in amperes.
Which best describes Jodi's error?
Electrons move from areas of high to low electric potential.
Which two wire properties would provide the greatest resistance to the flow of a current?
long, thin

Sagot :

Because it is an excellent conductor, copper is used for the majority of electrical wiring, and shorter cables reduce the resistance of wires carrying an electric current.

1)smaller wires

2)NOT X: Electron flow

Y: Lots of potential energy

Z: Minimal potential energy

3)Volts

4) It has strong conductivity.

5) The charges move more slowly in current Y because of the larger potential difference.

6)NOT

insulator,

semiconductor,

conductor,

superconductor

7)Differences in electric potential  

8) a cold slice of lead metal

9) Electrons flow between regions with high and low electric potential.

10) long and lean

The copper produced by electrolysis is known as pure copper or electrolytic copper. Numerous types of electrical wiring use copper as its electrical conductor. Electricity is produced, transmitted, and distributed via copper wire in telecommunications, electronic circuits, and a variety of other electrical devices.
