Answer 9

Measurements of two electric currents are shown in the chart.


Which best compares the two currents?

Current X has a greater potential difference, and the charges flow at a slower rate.
Current Y has a greater potential difference, and the charges flow at a slower rate.
Current X has a greater potential difference, and the charges flow at a faster rate.
Current Y has a greater potential difference, and the charges flow at a faster rate.

Answer 10

Current Y has a greater potential difference, and the charges flow at a slower rate.

Answer 11

Which best explains why an electric toaster is considered a resistor?

It increases the flow of electrons.
It acts as a conductor.
It converts electric energy to another form of energy.
It creates an increase in voltage within the current.

Answer 12

It converts electric energy to another form of energy.

Answer 13

Superconducting magnets are used in machines called particle accelerators. These machines rely on zero resistance in order to function properly.

How are the magnets able to have zero resistance?

They are heated to extremely high temperatures.
They are cooled to extremely low temperatures.
They are made to be very thick.
They are made to be very thin.

Answer 14

hey are cooled to extremely low temperatures.
