Electricity
What is electricity?
Electricity is the flow of electrical power or charge.
What are the 3 sources of electricity?
what is the definition of electric field?
A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
What are the 2 types of electricity?
There are two types of Electricity, Static Electricity and Current Electricity.
What is the definition of the word static?
Static means stationary or still.
What is static electricity?
Static Electricity is made by rubbing together two or more objects and making friction while Current electricity is the flow of electric charge across an electrical field.
What is current electricity?
Current electricity is the electricity that moves.
How do we measure electric current?
Current can be measured using an ampere.
What will happen without electricity?
Most importantly, many services integral to the functioning of the society would be put to a halt.
Why was electricity created?
People wanted a cheap and safe way to light their homes, and scientists thought electricity might be a way.
Who discovered the static electricity?
Ancient Greeks discovered the static electricity.
Who theorized that the universe is made up of tiny particles?
The Greek philosopher Democritus theorized it.
What does eureka mean?
It means the cry of joy.
Did you know that Alhazen ibn Al-Haytham disproves that the human eye can see everything because it creates its own light?
What is the meaning of heliocentric universe?
Heliocentric universe means the sun is at the center and the planets orbit around it.
How did Galileo come up with his theory?
He came up with his theory by dropping cannonballs of different sizes from great heights and shows that they all hit the ground at the same time.
What is Galileo’s theory about inertia?
The idea that objects will keep going or stay still unless a force is acting with them.
What did Newton publish in 1687?
He published the Principia Mathematica.
How did Benjamin prove that lightening is a type of electricity?
He proved it when he flied a kite in a thunderstorm and the kite got hit by lightning.
What is electromagnetism?
Electromagnetism is the physical interaction among electric charges, magnetic moments, and the electromagnetic field.
What did James Clerk Maxwell realize about electromagnetism?
He realized that electricity and magnetism are not separate phenomena.
Did you know that electromagnetism radiation can penetrate solid objects?
Did you know that an object can store energy as the result of its position?
What happen when you release a ball from a certain height above the ground?
It will drop automatically to the ground where the potential is lower. similarly, charge flows from the conductor at a higher potential to the one at a lower potential.
What is magnetic field?
The magnetic field is the area around a magnet in which there is magnetic force.
What is magnetism?
Magnetism is the force exerted by magnets when they attract or repel each other.
How does electromagnets work?
All electromagnets work on the principle that an electric current in a wire produces a magnetic field.
