Electricity Final Flashcards
proton
positivity charged
electron
negativity charged
Chemical Energy
stored in chemicals, energy is released when chemicals react.
Electrical Energy
the energy in charged particles, this enerfy is transferred when electrons travel from place to place
Mecahnical Energy
the energy possessed by an object because of it’s motion or its potential to move
Thermal Energy
total kinetic energy of all the particles in a substance. the faster a particle moves the more kinetic energy it has
ex. heat
thermocouple
a device that can convert thermal energy to electrical energy
electromagnet
coil of insulated wire that becomes a magnet when current flows through it
commutator
reverses the flow of electricity through the electromagnetic coil
armature
rotating shaft and coil in a motor
direct current
electricity flows in only one direction
alternating current
electricity flows back and forth
transformers
change the amountof of voltage with hardly any energy loss
electromagnet induction
generation of electric current in a conductor by a changing the magnetic field
DC generator
electrical machine that converts mechanical energy into direct current electricity
