Electric Charge
This particle in an atom has a negative charge.
What is an electron?
The net movement of electric charges in one direction
What is electric current?
When you close the circuit.
When does the current flow?
Static Electricity
What is the net accumulation of electrical charges on an object?
Provides a path for electric charges to move to the Earth.
What is grounding?
The buildup of electric charges on an object
What is static electricity?
The electric force that makes charges move.
What is voltage difference? (Measured in Volts)
Turning a switch off opens a circuit.
How do you break the path of a current?
Plastic, glass, and wood are examples of these.
What are insulators?
Measured in Volts
Voltage difference
A charge can be transferred from object to another but, cannot be created or destroyed
What is the law of conservation of charge?
A closed path that electric current follows
What is an electric circuit?
A circuit with only one path for the current to flow.
What is a series circuit?
Allows electrons to move through it easily
What is a conductor?
Has only one loop for current flow
What is a series circuit?
The transfer of charges by touching or rubbing.
What is charging by contact?
The tendency of a material to oppose or go against the flow of electrons.
What is resistance?
A circuit that has more than one path for the current to flow but each load has the same amount of voltage.
What is a parallel circuit?
Measured in Amperes (Amps)
What is current?
Two or more paths lower the resistance
What are parallel circuits?
A region in which charged particles attract or repel.
What is an electric field?
The temperature, length, and thickness of a material.
What can affect resistance?
Safety devices that stop wires from getting too hot.
What are fuses and circuit breakers?
Conductivity is between that of conductors and insulators.
What is a semi-conductor?
Stops current flow when wires overheat
What are fuses and circuit breakers?
