Electric Charge
the 3 ways charges can be transferred
friction, induction and contact
the unit for electric currents
amperes
what is an electric circuit
a complete, closed path through which electric charges can flow
what is a magnet
any material that attracts iron
what are electronics
any device able to control the flow of electrons using integrated devices
definition of electric charge
a property that leads to electromagnetic interactions between particles that make up objects
electric current only flows in one direction
what are the three basic parts of a circuit
an energy source, electrical conductor and a load
what is magnetic force
a push or pull exerted by two magnets brought together
what is an integrated device
a tiny chip that contains multiple circuit parts
what is induction
a way of rearranging electrons in an object without touching it
what is voltage
the amount of work required to move each unit of charge between two points
what is a load
a device that uses electricity to operate
what are domains
groups of atoms that form tiny areas (like a magnet in an object)
what is an analog signal
signals that change continuously
what is conservation of charge
charging if a transfer of electrons, so no electrons are actually lost
what has higher resistance, a thin wire or thick wire
thin wire
what type of circuit has multiple paths
parallel circuit
what are the three types of magnets
ferromagnets, electromagnets and temporary magnets
what makes digital code better that sending information
only sends in two values and is not affected by noise
