Conductor and 3 examples
A material that allows electricity to pass thru
1. Knife
2 Fork
3.Spoon
Anything metal
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
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
300
Insulator
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.
400
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
400
Draw a series circuit
A circuit where 2 or more components are connected end to end to form a single path.
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.3. Lightening
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
