Electricity
Question | Answer |
---|---|
A force that pushes a current through a circuit | Voltage |
friction that impedes flow of current through the circuit | Resistance |
the actual “substance” that is flowing through the wires of the circuit | Current |
Electrical currents are measured in | Amps |
An electric current is a flow of microscopic particles | Electrons |
are broken and do not allow the flow of electrons | Open Circuits |
are complete and allow the flow of electrons | Closed Circuits |
Devices connected in series to prevent the overloading of circuits | Fuses |
the presence and/or flow of electric charges | Electricity |
control the movement of electric current by providing paths for electrons to follow | Circuits |
there is only one path for the electric current or electricity to flow | Series Circuit |
there is more than one path for the electric current or electricity to flow. | Parallel Circuit |
can be used to test whether an object is a conductor or an insulator. | Open circuit |
A material, such as wood or glass, which electrons do not move freely | Insulator |
A material, such as cooper or silver, which electrons move freely | Conductor |
A material which electricity has trouble flowing through | Resistor |
Electrical potential of an electron | Voltage |
