Static and Current Electricity

Electricity is________

• the presence and flow of electrons in two directions.

• the presence and flow of electrons in one direction.

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

• Current electricity involves a continuous flow of elecrons; 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

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

In the circuit, if you replace the paper clip with a plastic spoon, what would happen?

• The bulb wouldn't light

• The bulb is dimmer

• The bulb is brighter

• There is no change

Electrical charge built up on the surface of an object is called _________________.

• static electricity

• current electricity

• lightning

• electrons

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

• The doorknob sends a burst of electric current into your body

• Millions of electrons go from your finger into the doorknob

• The doorknob sends millions of electrons into your finger

• Your finger becomes negatively charged

A series circuit has ____ path(s) that the electric current can take. 

• One

• Two 

• Three 

• Four

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current is divided between the three light bulbs.

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

• Static electricity is the flow of electrons; current electricity is the accumulation of charge.

• Static electricity involves a single transfer of electrons; current electricity involves a continuous flow of electrons.

• Static electricity is always dangerous; current electricity is always safe.

• Static electricity is used in batteries; current electricity is used in capacitors.

Which of the following is an example of static electricity?

• A lightning bolt striking a tree

• A battery powering a flashlight

• A fan running on electricity

• A toaster heating bread
