Electricity I
Materials that allow electric charges to flow through it easily
Electrical conductor
How you get a balloon to stick to your head
static electricity
A device that can open or close a circuit.
switch.
Oppositely charge objects _____________ each other.
attract.
Which is a good electrical conductor: A) plastic B) wood C) rubber D) metal
D) metal.
The ability of a material to impede the flow of charge
Resistance
_____________ is when an electrical wire and a bulb are connected as a circuit which generates electric current.
Closed circuit
Electrons in a circuit are pushed away from a battery's ____________ pole.
negative.
The way current is drawn on circuit maps, but it's not actually the way the electrons flow.
Conventional current
A battery converts chemical energy into _______________.
electrical energy.
The amount of charge that travels past a fixed point in an electric circuit each second
Electric current
The invisible region around any charged object
electric field
When a force is applied to keep two unlike charges apart
electric potential energy
Charging an object without direct contact between the object and a charge
Induction
Path of electric charge
Electric circuit
An object in an electrical circuit that does not allow the flow of electrons.
insulator
A circuit that does not have a complete connection between the two sides of the power source. As a result, current does not flow.
Open circuit
An example of insulator
rubber, wood, glass, paper, cloth
Energy generated by the movement of electric charges
Electrical power
Electrical current is the flow of moving _______________.
electrons.
Charging an object by allowing it come into contact with an object that already has electrical charge
Conduction
A ____________ is a material that current can pass through easily, like metals.
Conductor
Electrons in a circuit are pulled toward the battery's __________ pole.
positive.
The electrical potential energy difference between two places on a circuit
Voltage
It provides energy, making electrical charges move in the circuit.
Battery or Source of electricity
