what is renewable energy?
energy that can be replaced continually and will never deplete
examples for renewable energy
hydro
solar
biomass
tidal
wave
what is non renewable energy?
energy that cant be replaced and will deplete
examples of non renewable energy
coal
nuclear
coal
petroleum
what is magnetic flux?
number of magnetic field lines in an area
what is induced current?
a current produced in a circuit when theres a magnetic flux
how to produce electricity?
magnet has to not be stationary, coil cant be stationary (either one)
non renewable energy mechanism?
burning of fuel → boiling water produce steam → turbine → generator
solar energy mechanism?
sunrays → solar panel convert light energy to electricity
non renewable energy energy change?
chemical → heat → kinetic → electrical
solar energy energy change?
solar energy → electrical energy
hydroelectric power station mechanism
high dam stores water → water flows from high levels to low levels → flow of water rotates turbine generator produces electricity
hydroelectric energy change
gravitational potential energy → kinetic energy → electrical energy
wind energy mechanism
moving air → wind moves blades → blade rotate turbine → generator prodces electricity
wind energy change
kinetic energy → electrical energy
nuclear energy mechanism
nuclear reaction → boiling water produces steam → steam rotates turbine → generator produces electricity
nuclear energy change
nuclear energy → heat → kinetic → electric
biomass mechanism
biomass produces methane → boilinb water produces steam → turbine → electricity
biomass electric change
chemical → heat → kinetic → electric
direct current characteristics
uses battery source, one way
alternating current characteristic
constantly reversing directions
whats cathode ray oscilloscope for?
to show the difference in the shape of graph, direction of current and voltage change for direct current and alternate current
