What is electric discharge?

The sudden and brief flow of electrons

The sudden and brief flow of protons

The sudden and brief flow of neutrons

A material that allows electric current to flow easily

A material that stops electric current from flowing

What is an insulator?

A material that DOES NOT allow electric current to flow

A material that DOES allow electric current to flow

What is static electricity?

The buildup of electric charges on an object

How do you increase the strength of an electromagnet?

Increase the electric current and increase the number of coils

Decrease the number of batteries and increase the number of coils

Increase the electric current and decrease the batteries

Ms Jo Jo rubbed two balloons with a piece of wool. What will happen when the balloons are brought near each other?

The balloons will repel each other.

The balloons will attract each other.

The balloons will become positively (+) charged.

What is the major difference between static electricity and current electricity?

Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons

Current electricity involves a continuous flow of neutrons; static electricity is a sudden transfer of protons

Current electricity can be deadly; static electricity is almost always safe

In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons

What happens when you touch a metal doorknob after rubbing your shoes on the carpet?

Millions of electrons go from your finger into the doorknob

The doorknob sends a burst of electric current into your body

The doorknob sends millions of electrons into your finger

our finger becomes negatively charged

Which of the following is caused by static electricity?

a lightning strike during a storm

a stove getting hot when it is turned on

a magnet being attracted to a refrigerator

a light bulb coming on when a switch is turned on

Lightning is a form of static electricity. What can you infer about what happens when lightning strikes the ground?

Electrons are transferred from the clouds to the ground.

Protons and neutrons are transferred from the clouds to the ground.

The ground becomes negatively charged.

An electric current is established between the clouds and the ground.

If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

the silk has become negatively charged.

friction destroyed electrons in the rod.
