Anika, Rohan, and Henry are studying for their physics exam. They come across a question about a type of electric current that continually reverses direction over time. What is this type of current called?

• direct current

• alternating current

• simple current

Grace, Elijah, and Ava are working on a science project. They need to create a circuit where the electric current flows in one direction only. What is this type of current called?

• voltage

• parallel current

• direct current

• electric current

Sophia is working on a science project about electricity. She learns that resistance is...

• What "slows down" electrons in a wire

• What "speeds up" electrons in a wire

• Moving electrons in a wire

• What "pushes" electrons in a wire

Current is...

• moving protons

• moving electrons

• measured in volts

• measured in ohms

The two types of current are...

• AC/DC

• Alternating Current

• Direct Current

• All of the above

___________ wires keep electrons on course & protect us from the dangerous flow of electricity. 

• Insulated

• Conducted
