Electricity (two types)

Question 1

What is electricity?

Answer 1

Electricity is the flow of negatively charged electrons. Some electrons can break free from their atoms and these free electrons are attracted to nearby atoms and attach themselves, pushing out another electron in this process. This creates a chain reaction where electrons keep moving from one atom to another
This continuous movement forms an electric current, which flows through a conductor/wire

Question 2

Electrostatic force

Answer 2

a non-contact force between charged particles. It can be attractive (a positive charge pulling a negative charge) or repulsive (two positive charges pushing each other away).

Question 3

Static electricity

Answer 3

Build up of electric charge on an object’s surface. Caused by imbalance of electric charges on the surface of materials and happens through friction or direct contact.
Charges remain until suddenly discharged.
Can cause sparks or shocks.
Does not flow through a circuit.
Usually brief and temporary.

Question 4

Current electricity

Answer 4

Continuous flow of electrons through a conductor. Powered by batteries, generators or power sources. Flows through a close circuit.
Transfers energy steadily to power devices. Can last as long as the power source is connected.

Question 5

Electrostatic Discharge

Answer 5

A sudden release of built-up static electricity caused by rapid movement of electric charges.
It can happen when electricity jumps through the air, creating light, sound or spark.
This happens when the charges want to balance out and return to a neutral state.

Question 6

Conductors

Answer 6

Materials that allow current to flow easily
High current, low resistance
Have free-moving electrons
Usually metals like copper or aluminum
Used in wires and circuits

Question 7

Insulators

Answer 7

Blocks or resists electricity to flow
Low current, high resistance
Electrons are tightly held
Made of materials like rubber, plastic or glass
Used for safety and wire coating
