Question

chapter 22 \electricity\ test

rapid movement of excess electrons from one place to another is ____

○ electric discharge

○ electric field

○ electrical power.

○ electric current

Explanation:

To solve this, we analyze each option:

• Electric Discharge: Involves sudden release of static electricity (like lightning), not rapid electron movement in a current - like flow.
• Electric Field: A region around a charge where force is exerted, not electron movement.
• Electrical Power: Rate of electrical energy transfer, not electron movement.
• Electric Current: Defined as the rate of flow (movement) of electric charge (electrons in this case) through a conductor. The rapid movement of excess electrons matches the definition of electric current.

Answer:

A. Electric Discharge (Incorrect, as explained)
B. Electric Field (Incorrect, as explained)
C. Electrical Power (Incorrect, as explained)
D. Electric Current (Correct, matches the definition of electron movement)

(Note: Assuming the options are labeled A - D as per typical multiple - choice, with the first option as A, second as B, third as C, fourth as D. If the original options have different labels, adjust accordingly. The correct option is the one with "Electric Current".)
