Question

question 23
an electric spark ____________.
results whenever electricity passes through a wire
is caused by a magnetic attraction
is an electrical charge suddenly released through the air
comes from too much heat buildup in a wire
question 24
1 pts
what two types of electric charges are needed to create static electricity?
negative and negative
positive and positive
negative and positive
no charge is needed

Explanation:

• For Question 23: An electric spark occurs when there is a sudden discharge of electrical charge through the air. Electricity passing through a wire (without a breakdown of the air - wire insulation interface) doesn't cause a spark. Magnetic attraction is not related to electric sparks. Heat buildup in a wire is related to Joule heating, not sparks.
• For Question 24: Static electricity is created due to the separation of positive and negative charges. Like charges (negative - negative or positive - positive) repel each other and do not create the necessary charge imbalance for static electricity. And static electricity is based on charge separation, so charge is needed.

Answer:

Question 23: is an electrical charge suddenly released through the air
Question 24: negative and positive
