Grade 9 Electricity Quiz Questions And Answers
(47).jpg "Grade 9 Electricity Quiz Questions And Answers - Quiz")
We have this Grade 9 electricity quiz for you. An electric current is a flow of electric charge. In electric circuits, moving electrons in a wire often carries this charge. Electrical hazards can cause burns, shocks, and electrocution (death). Test your knowledge of electricity, its production, and safety techniques through the test below. All the best as you explore this quiz! We hope you score high on this quiz. Let's go!

Receiving an electric shock from a doorknob is an example of ____________.
- A.
Static electricity
- B.
Current electricity
- C.
Spontaneous electricity
- D.
None
Correct Answer
A. Static electricityExplanation
Receiving an electric shock from a doorknob exemplifies static electricity. This occurs when objects build up an imbalance of electric charge due to friction or contact with other charged objects. When you touch a doorknob, the accumulated static charge on your body discharges suddenly, resulting in a brief but noticeable electric shock. Static electricity is distinct from current electricity, which involves the continuous flow of electrons through a conductor.Rate this question:

What should you not bring near an electric appliance?
- A.
Water
- B.
Plastic
- C.
Wind
- D.
Rubber
Correct Answer
A. WaterExplanation
You should never have an electric appliance near water or other liquids because those are good conductors of electricity. This could cause you to get shocked.Rate this question:
