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.
