100
A mechanical device that runs in water that is equivalent (analogous) to electric appliances, light bulb, toaster, TV, air conditioner, electric tooth brush and uses resistance to run.
What is a water wheel
100
A unit of measure for the flow of current in a circuit, C/s
What is an amper
100
The condition of most matter when negative charges of a substance equal the positive charges within or on an object , zero net charge
What is neutral
100
A device similar to a fuse in function that protects a circuit from current overload
What is a Circuit breaker
100
A device that contains a metal strip that melts when current in the circuit becomes too great
What is a fuse
200
These provide most of the electrons in the circuit and make a path through which electricity travels. Usually made of metal
What is a wire
200
states that when an electric current is flowing through a conductor, such as a wire, the intensity of the current (in amperes) equals the electromotive force (volts) driving it, divided by the resistance of the conductor. The flow is in proportion to the electromotive force, or voltage, as long as the resistance remains the same. Current is equal to Voltage divided by the resistance
What is Ohm’s Law
200
The relationship between current and resistance
What is inverse
200
as a metal is heated the resistance will do this
What is Increases
200
The relationship between current and voltage
What is direct
300
It is caused by a buildup of excess charge on clouds, usually negative charges. Some people are frightened by it, while I like it
What is lightning
300
These are similar as both transfer particles and are controlled by valves and switches
What are Water pipes and wires
300
A device that measures or identifies unknown charges
What is an Electroscope
300
Usually means the flow of electric current with electrons in wires, motors, light bulbs, and other electrical devices
What is Electricity
300
It is like water, except it flows through solid metal so we can’t usually see it and it can carry energy over great distances
What is a Current
400
A circuit with a switch in the off position or a break in the wire
What is an Open circuit
400
Fundamental unit of electrical charge on an electron, approximately equal to 1.602×10―19
What is a Coulomb
400
Flow of electrons which reverses its direction at regular intervals in a conductor as used in your house and throughout the USA, Its frequency is 60 cycles / second
What is Alternating current
400
An electrical network or path that has a closed loop giving a return path for the flow of current (electricity)
What is a circuit
400
A steady flow of electrons moving steadily and continually in the same direction. The quantity is produced by a battery or generator.
What is a Direct current
500
Low density materials that do not allow electricity to pass through easily. The tightly held electrons around the atoms hinder the flow of electrons and heat.
What is an Insulator
500
Standard unit for measuring resistance to flow in an electrical current.
What is an Ohm
500
Occurs when a circuit is broken, such as a broken wire or switch on the off position, interrupting the flow of current through the circuit.
What is an Open circuit
500
All components in the pathway are connected, switches are on and electric is free to flow
What is a Closed circuit
500
Circuit components are arranged in branches so that there is a separate path to each unit along which electrical current can flow. Example is the newer Christmas lights.
What is a Parallel circuit
