This occurs when a positive and negative charge is no longer balance.
What is static electricity?
100
This is an electric charge that can flow in only one circular path.
What is a series circuit?
100
Electricity, light, sound, and energy of motion.
What are some of the different forms of energy?
100
List three appliances that transform electrical energy into another form of energy.
What is a toaster, porch light, electrical stove burner etc..
100
A material through which an electric charge can move easily.
What is a conductor?
200
Some of these can have a positive charge(+), a negative charge (-) or no charge.
What are the three particles of an atom?
200
This has two or more paths through which electric charges may flow.
What is a parallel circuit?
200
This is a thin, coiled wire that can get very hot without melting.
What is a filament?
200
Suppose you have a set of lights that are wired in a parallel circuit. What will happen if one bulb burns out?
What is the other lights stay on?
200
How can objects transform electrical energy?
What is objects with resistors change electrical energy into light and give off heat?
300
This is an electric charge in motion. It flows quickly and invisibly from one place to another.
What is an electric current?
300
In a series circuit, any break in the loop can result in this.
What is a stop in the current from flowing?
300
Electricity can change into this form of energy.
What is light?
300
A flashlight is a series circuit that has a battery as its energy source. Describe what happens in a flashlight when the switch is turned from off to on.
Turning the switch closes the circuit. Energy from the battery flows though the circuit and lights the bulb.
300
A good energy source for a simple circuit is this.
What is a battery?
400
This is a material through which an electric charge can move easily.
What is a conductor?
400
This has an energy source, like batteries and electrical outlets. It has wires in which charges flow. It also has resistors such as light bulbs or machines.
What are circuits?
400
Motion can change into this type of energy.
What is sound?
400
About 75 percent of the energy that passes through a fluorescent bulb is used as light. If a fluorescent bulb is on for 2,000 kilowatt-hours, how much energy is used as light?
.75 x 2000 kWh=1500 kWh
75 percent=75/ 100
400
Describe how a filament in an incandescent light bulb transforms electrical energy.
It is a resistor that gets very hot and gives off light when electrical energy flows through it.
500
This is a material through which an electric charge moves with difficulty. It can be made of plastic, rubber, or dry wood.
What is an insulator?
500
In this circuit, if one loop is broken, the current will still flow.
What is a parallel circuit?
500
Wind can change into this type of energy.
What is electricity?
500
What material would be the best insulator for a metal wire?
