Conductor and 3 examples
A material that allows electricity to pass thru
1. Knife
2 Fork
3.Spoon
Anything metal basically
100
Electrical energy can be transformed to 3 types of energy. Name them
Mechanical, radiant, thermal energy
100
What is an electromagnet
When you pass an electric current through a coil of wire, the Nail becomes magnetic.
100
What does a simple circuit consist of
Light bulb, battery, 2 wires
100
What are the ages of the people in your group?
What is the average age?How?
Add up the ages of your group and divide by the number of people in your group.
For correct answer show all ages and show answer
AMV
200
Open Circuit
A circuit that will not allow the transfer of electricity
200
Give an example of transforming electrical energy to mechanical energy
Ceiling fan
200
What will happen to the material being held by an electromagnet if the circuit is opened.
The material will no longer be attracted to the magnet
200
What can you introduce into a simple circuit to open and close the circuit?
A switch
200
How is lightning static electricity?
it is a large-scale example of a sudden discharge of built-up electrical charges, just like the smaller static shocks you experience when touching a charged object; in a thunderstorm, these charges accumulate within the cloud due to the collision of ice particles, creating a significant potential difference that eventually discharges as a lightning bolt when the electric field becomes strong enough to overcome the air's insulating properties
300
What is an insulator and give three examples.
Any item that prohibits electricity from passing thru
1. Rubber
2. Cork.
3. Paper
300
Give an example of transforming electrical energy to Radiant energy
Light
300
What material is needed to make a simple electromagnet
Power source- battery
2 wires
Nail
300
Why when creating a simple circuit can you not have one end of one of the wires end on the glass part of the light bulb
The glass is an insulator and will not transfer the electricity , interrupting the flow of energy.

Closed Circuit
A circuit that allows electricity to pass through
400
Give an example of transforming electrical energy to thermal energy
Oven
400
To increase the power what can you do to the coils
Increase the number of coils around the nail, which increases the power
400
Draw a series circuit
A circuit where 2 or more components are connected end to end to form a single path.
400

500
Static Electricity
Give three examples
a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair. Negatively charged particles transferred.
Ex. 1.Taking a wool hat off your head clothes in the dryer.2. Lightning 2. Water being pushed away from a charged balloon.
500
What is the charge of the particles transferred with static electricity
Negative
500
What is another option to increase the power?
Get a stronger power source
500
Draw a parallel circuit
500
How does a switch work
A switch breaks the flow of electricity by making a closed circuit and open circuit so there is not a continues flow of electrons back to the power source.
It can also reestablish the flow by closing the switch.
