Science Electricity Flashcards
Explain why insulating materials do not conduct electricity.
Insulators do not conduct electricity as they have a high resistant.
Why is Copper used instead of silver?
Copper is used instead of silver because Copper is cheaper and more affordable.
Is the human body a good electrical conductor?
Yes
Why is the human body a good electric conductor?
Water is a conductor and the human body is 55% to 65% of water.
How do insulating sheaths protect us from electrocution?
The sheaths helps us from being electrocuted as the plastic wouldn’t allow it to flow.
What is a closed circuit?
A closed circuit is a circuit without interruption, providing a continuous path through which an electric current can flow.
What is a series circuit?
A series circuit is a circuit where all components are connected end to end to form a single path for electric current to flow through.
What is a parallel circuit?
A parallel is circuit where it has two or more paths for electric current to flow through and the loads are parallel.
What is kinetic energy?
Kinetic energy is the energy an object has because of its motion.
Which What two types of energy are produced when a light bulb lights up?
Light and Heat energy are produced.
