Question | Answer |
---|---|
A complete circuit, where electricity flows from one battery terminal, through the circuit and back to the other battery terminal | closed circuit |
material through which energy moves | conductor |
a form of enrgy which can be transferred from one place to another in a closed circuit | electricity |
a resistant wore in a bulb which transfroms electrical energy into light energy | filament |
a strip of easily melted metal placed in a circuit as a safeguard | fuse |
a device to prevent the passage of electricity often called a nonconductor | insulator |
a wire that has a relatively high resistance and heats up as an electrical current runs through it | nichrome wire |
a circuit which provides multiple paths through which electricity can flow | parallel circuit |
the condition of having positive and negtive ends which must be aligned correctly for the batteries to be in series or parallel | polarity |
a property of a material which describes how much it restricts the flow of electricity | resistance |
a circuit that has only one path through which electricity can flow | series circuit |
an accidental connection between two points in an electrical circuit which allows electricity to follow a different path of low resistance | short circuit |
a device in an electrical circuit that opens and closes the circuit | switch |
points which must be touched in order to make a complete circuit | terminals |
a unit used to measure electrical energy | volt |
What kind of circuit gets brighter when you add more batteries? | series |
What kind of wire is more resistant to the flow of electricity? A thick wire or a thin wire? | thin |
