Electricity Flashcards
What is electric charge
Electric charge basic prop;erty that determines how the particles will move in an electric or magnetic field
Proton
Positive, nucleus, p+
Neutron
Nutral, nucles n0
electron
negative outside the nucleus, e-, only that can move
neutral object
overall charge of zero, equal amounts of protons and neutrons
Positively charged object
overall positive charge, more protons than electrons
Negatively charged object
overall negative charge, more electrons than protons
Electric force
attraction or repulsions of particles or object because of their electic charge
Coulomb’s law
like charges will repell eachother unlike charges attract
Source
Cell or battery, provides power to the circuit
Connector/wire
wire, electrically conductive materials which allow the folow of electrons
Switches:
Switch-used to control the flow of electrons: start and stop
Fuse: if more electricity flow through a fuse than it was designed for, the thin wire of the fuse heats up so much that it melts creating a gap
Loads
Light/resistor/motor, use the energy provided by the electorn flow to do work
Current
a measure of the quantity of a charge passing any point of the wire per unit of time, (symbol I), unit of measurement, Ampere (symbol A), amount of electrons passing per second
Potential difference
the difference in the amount of energy that electrons have between two points in a circuit, symbol V, Unit of measure Voltage (symbol V), measured used voltmeter, amount of electrical push amount of electic work that can be done.
