Question

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?

The movement of electrons is not always continuous.
Electrons move from areas of high to low electric potential.
Resistance causes current to flow.
The rate at which current flows is measured in ohms.

Answer 1

"The movement of electrons is not always continuous."

Explanation: In DC circuits electrons have a slow steady drift, but in AC they oscillate back and forth (not a continuous one‑direction flow). The other three statements (electrons move from low to high potential, voltage drives current, and current is measured in amperes) are essentially correct.
