200
The movement of electrons to one part of an object that is caused by an electric field of another object.
What is induction?
200
A complete, unbroken path through which electric charges can flow.
What is an electric circuit?
200
The loss of static electricity as electric charges transfer from one object to another is called Static Discharge. That means a negatively charged object and positively charged object when brought together, will have electrons transfer over until both objects have the ___________ charge.
What is the Same charge?
200

How does an electrochemical cell work?
What is: A chemical reactions occurs between the electrolyte and electrodes in an electrochemical cell. These reactions cause one electrode to become negatively charged and the other electrode to become positively charged.
300
A device used to measure current.
What is an ammeter?
300
The continuous flow of electric charges through a material
What is Electric Current?
300
There are two ways to Break a circuit, name one way.
What is a Fuse/ Circuit Breaker.
300
Voltage divided by Current is equal to what?
What is Resistance?
300
How are conductors different from insulators?
What is: Insulators will not allow charges to flow easily through them, conductors will.
400
A process in which substances change into new substances with different properties.
What is Chemical Reaction?
400
Resistance is the measure of how difficult it is for charges to flow through a material. The greater the resistance, the _________ current there is for a given voltage.
What is the Less current there is for a given voltage?
400
This round part of a plug connects any metal pieces of the appliance to the ground wire of the building.
What is the Third Prong?
400
This circuit has several paths for the current to take.
What is Parallel Circuits?
400
What is an electric field?
What is: A region around a charged object here the objects's electric force is exerted other charged objects.
500
A substance that conducts electric current. (Volta used salt water)
What is an Electrolyte?
500
There are four factors that determine the resistance of a wire, or any other object. Name one of the four factors.
What is the Material that the wire is made out of, the Length of the wire, the Diameter of the wire, the Temperature of the wire.
500
There are three features of a circuit, name one.
What are: circuits have devices that are run by electrical energy, has a source of electrical energy, are connected by conducting wires.
500
To find ____________ you multiply Voltage and Current.
What is Power?
500
What factors are used to determine how people pay for electrical energy?
What is: the total amount of energy used by an appliance is equal to the power of the appliance multiplied by the amount of time the appliance is used.
