any material which transfers electric charge well because the electrons are loosely bound and can move freely (metals, wire)
What is a conductor?
100
A device that creates a potential difference in an electric circuit (ex. battery, generator)
What is Voltage Source?
100
not continuous; it is a sudden burst of electric charge that does not flow
What is static electricity?
200
This is the correct name for what people call a "battery"
What is a cell?
200
The type of cell that the electrolyte is a liquid.
What is wet cell?
200
Any material that does not allow electric charges to flow because the electrons are bound tightly together and do not move freely (wood, paper, and, glass, rubber, plastic)
What is an insulator?
200
The rate of current; the number of charges flowing past a point in one second
What is Amp?
200
The measure of how difficult it is for the electric charges to flow through a material; if resistance is high, the current is low and vice versa
What is Resistance?
300
A device that controls the flow of electric current by closing or opening the circuit
What is a switch?
300
Two or more electrochemical cells connected together
What is a battery?
300
An unbroken path on which the charges flow
What is a Complete Circuit?
300
The difference in electrical potential energy between two places in a circuit; voltage causes a current in a circuit; (the force pushing the electric current)
What is voltage?
300
The 4 factors of resistance:
What is length, temperature, material and diameter?
400
The substance in which the electrodes are immersed within the electrochemical cell
What is an electrolyte?
400
He built the first electric battery by layering zinc and silver in between paper soaked in salt water.
Who is Alessandro Volta?
400
A broken path; the charges cannot flow
What is an Incomplete Circuit?
400
The two disadvantages of a series curcuit are?
What is a burned out bulb or removing a bulb breaks the curcuit and the other bulbs go out and the more bulbs that are added, the dimmer the bulbs become.
400
The voltage of most typical homes in America
What is 120 volts?
500
The part of the electrode above the electrolyte
What is a terminal?
500
A device that changes chemical energy into electrical energy
What is an electrochemical cell?
500
A _________________________is a circuit with only one path for the electric charges to take.
A ________________________ a circuit in which there are several paths for the electric charges to take
What is series and parallel?
500
There are two advantages of using a paralle curcuit.
What is : if one bulb goes out, the rest will stay lit because there are multiple pathways for the current; the more bulbs added, the current stays the same so the bulbs all burn just as brightly
500
There are three parts of a curcuit.
What are...
1. resistor - circuits have devices that are run by electric energy
2.energy source - a circuit has a source of electrical energy
3. current - electric circuits are connected by conducting wires
