Question

which best describes a difference between electric current and static electricity?
○ electric current is continuous, and static electricity is not continuous.
○ static electricity is continuous, and electric current is not continuous.
○ electric current involves the movement of electrons, and static electricity involves the movement of protons.
○ static electricity involves the movement of electrons, and electric current involves the movement of protons.

Explanation:

To solve this, we analyze each option:

• Option 1: Electric current is a continuous flow of electrons (e.g., in a circuit), while static electricity is a buildup of charge (not continuous flow). This matches the concepts.
• Option 2: Static electricity is not continuous (it's a charge buildup), so this is incorrect.
• Option 3: Static electricity involves electron transfer (not protons, as protons are in the nucleus and don't move freely in most cases), so this is wrong.
• Option 4: Electric current involves electron movement (not protons), so this is incorrect.

Answer:

A. Electric current is continuous, and static electricity is not continuous.
