Energy Consumption
energy made from a resource that CAN be re-used or replaced like solar energy, wind energy, and water energy.
Renewable energy
the amount of power an electrical device consumes in one hour of usage. Measured in watts (W) or kilowatts (kW)
Power Rating
Energy source that when the reactants (chemicals) are used up,it will no longer work.
primary battery
unit of measurement for charge (symbol is ‘C’). There are 6 280 000 000 000 000 000 electrons in 1C:
Coulumb
Neutralizing in an object by removing excess charge
grounding
energy made from a resource that CAN be re-used or replaced like solar energy, wind energy, and water energy.
non-renewable energy
an energy source that converts chemical energy into electrical energy. It has both a positive and a negative terminal.
Energy source that lets chemical reactions be reversed so they can be used again. This makes it rechargeable.
secondary battery
unit of measurement for current (symbol is ‘A’). It is calculated by the amount of charge moving past a point divided by the amount of time)
Amps
when a charged object is brought close to a neutral or oppositely charged object, the electrons will jump through the air from the more negative object to the other.
electrical discharge
a rotating machine that uses the wind’s power to spin its blade causing gears to rotate, converting the wind energy into electrical energy. When many are placed in one area it is called a “wind farm”
wind turbine
a continuous flow of electrons and electrical charge. In order to provide power it needs an energy source and a circuit path. It is usually generated at a power station and is carried into your home via hydroelectric wires.
current electricity
Chemical ions that conduct electricity. It is usually a liquid or a paste.
electrolytes
a unit measurement for potential difference which is independent of current flow.
Volt
electricity (usually generated by friction) that creates a stationary electric charge that covers a surface, which causes sparks or the attraction of dust or hair
static electricity
cells which convert light from the sun directly into electricity. Larger cells can power street lights, homes, or businesses.
Solar Cells OR Photovoltaic Cells
materials where the charge on an object does not stay in the spot. It easily spreads out evenly over the surface allowing electrons to move freely through.
conductors
a path for the flow of electrons to travel. It needs an energy source, a conductor, and a load. The energy source (battery) is used up by pushing the current (flow of electrons) around it.
circuits
the opposition to current flow (measured in Ohms, Ω) that takes the energy from electrons as they flow through
resistance
materials that are able to attract other materials upon being rubbed
charged
Non-renewable fuels collected from the ground (land or ocean) that come from fossilised organisms that lived many years ago collected from the ground.
Fossil fuels
materials where the charge on an object stays in the spot where it was rubbed. It has tightly bound electrons and doesn't allow the transfer of electrons to other atoms.
insulators
the amount of charge that passes by a certain point in a wire per unit of time.
electrical current
the amount of potential energy that each electron has. This difference between two points creates force and "pushes" the electrons through electron wiring. It pushes, whether the electrons are moving or not.
Potential difference (voltage)
The flow of electrons
