The movement of ______ charged particles is an electric current.
- Explanation: Electric current is defined as the movement of charged particles (typically electrons). The term "charged particles" is already mentioned, so we need a term that describes the direction or nature of this movement.
- Correct Answer: DIRECT
Completed Sentence: The movement of direct charged particles is an electric current.
---
Portable devices such as flashlights often use ______ current.
- Explanation: Flashlights and other portable devices typically use direct current (DC), where the flow of charge is in one direction.
- Correct Answer: DIRECT
Completed Sentence: Portable devices such as flashlights often use direct current.
---
A simple circuit needs a source of ______ such as a battery.
- Explanation: A battery provides energy to power the circuit. The term "source of" suggests we need a term related to energy.
- Correct Answer: ENERGY
Completed Sentence: A simple circuit needs a source of energy such as a battery.
---
A simple circuit also needs a conductor such as a(n) ______.
- Explanation: Conductors are materials that allow electric current to flow easily. The most common conductors used in circuits are wires.
- Correct Answer: WIRE
Completed Sentence: A simple circuit also needs a conductor such as a(n) wire.
