Electricity
The set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.
Parallel circuit
A circuit that has more than one pathway for electrons to follow.
Series circuit
A circuit that has a single pathway for electrons to follow.
Electric charge
The ability of electric charge to move, which is essential for the utility of electrical energy.
Static electricity
The buildup of positive or negative charge on materials.
Current electricity
The energy of steadily moving electric charge, used by electric devices such as lamps and computers.
Circuit
A pathway for electrons to follow, allowing the flow of electric current.
Resistance
A measure of how much an object opposes the flow of electric current.
Equation of voltage is?
V= e/q units
Equation of current is?
I= q/t rate
Energy mass
it has no mass
Type of energy in a battery
chemical energy
Electrodes
conductors
electrolytes
solution with ions
primary battery
only one use
secondary battery
can be reused like phone battery
Fuel cells
chemical reactions for energy
Hydrogen fuel cell
H and O combine and make energy
DC
Moves in one way
AC
Moves both ways
Electrical energy
can not be found in nature
(A)
Amperes unit
Fuses
can cut off electric flow if too high. Only once
Cricut breakers
can cut off electric flow if too high. more then once
voltmeter
measures the load through specific load
Resistor
ability to appose the electric current
Unit Ohms
resistors
what effects resistance
too hot, too long, small cross section area, insulators/ materials
resistors use what to make current slower
energy, all loads are resistors
