Question

what can cause electrons to jump across a gap and cause a spark?
a. allowing a battery to run out of charge
b. charging a battery
c. an imbalance of charges between surfaces

Explanation:

• Option A: A battery running out of charge means no charge flow, so electrons won't jump to cause a spark.
• Option B: Charging a battery involves controlled charge transfer, not sudden electron jumps across a gap to create a spark.
• Option C: An imbalance of charges (like static electricity) creates a strong electric field, forcing electrons to jump across the gap, resulting in a spark.

Answer:

C. an imbalance of charges between surfaces
