🔍 Key Concepts

• Direct vs alternating current in basic electricity • How many directions the electrons flow over time • Common electrical terms used in DC vs AC circuits

💭 Think About

• Which type of current changes direction back and forth, and which type keeps flowing one way? • Look at the root word in each choice (for example, "alternating" or "direct"). What do those words mean in everyday English? • Which option name is actually used for batteries and simple DC circuits on small vessels?

✅ Before You Answer

• Match the word meaning to the idea of one direction only • Eliminate any answer choices that clearly mean changing or varying direction • Think about what you call the power that comes from a typical household wall outlet vs. from a battery
