Explanations: answer key for all 10 questions

Q1: Which particles move to create electric current in metal wires?
Answer: Electrons
Electrons drift through the metal when a voltage is applied.
Q2: What is electric current measured in?
Answer: Amperes
The ampere is named after French physicist André-Marie Ampère.
Q3: What does voltage represent?
Answer: The push that drives current
Higher voltage means more energy per charge.
Q4: Which law links voltage, current and resistance?
Answer: Ohm's law
Voltage equals current times resistance.
Q5: Which material is a good electrical insulator?
Answer: Rubber
Insulators stop current from flowing easily.
Q6: Why does your hair stand up after rubbing a balloon on it?
Answer: Static charges repel
Each hair gains the same charge and pushes away from the others.
Q7: Who flew a kite in a storm to study lightning in 1752?
Answer: Benjamin Franklin
He showed lightning is electrical.
Q8: What does a power plant generator use to make electricity?
Answer: Spinning magnets and coils
This uses electromagnetic induction.
Q9: What protects a home circuit from too much current?
Answer: A fuse or circuit breaker
It cuts the circuit if current is too high.
Q10: How fast does an electrical signal travel along a wire?
Answer: Close to the speed of light
The electrons themselves drift slowly, but the signal is fast.

Electricity Quiz – The Power of Moving Charges

Electricity is the flow or buildup of electric charge. In wires, tiny electrons drift when a voltage pushes them, creating current. Materials like copper conduct electricity easily, while rubber, plastic and glass resist it and are used as insulators to keep people safe.

Scientists such as Benjamin Franklin, Alessandro Volta, Michael Faraday and André-Marie Ampère uncovered how electricity works. Faraday's discovery of electromagnetic induction made generators possible, and by the late 1800s power plants were sending electricity to homes and factories.

Today electricity powers lights, phones, hospitals, trains and computers. It is generated from coal, gas, nuclear, wind, solar and hydro sources. Understanding circuits, voltage and safety devices helps us use it wisely and avoid dangers like shocks and fires.
