electrochemical cells
convert chemical energy into electrical energy
battery
electrochemical cell or multiple electrochemical cells connected together
terminals
end points of a battery where connections are made
negative terminal
end where electrons accumulate
positive terminal
end that has lost electrons
electrodes
battery terminals and the rod that connects them
electrolyte
conductive substance surrounding the electrode
dry cell
electrolyte is a moist paste
wet cell
electrolyte is a liquid
amount of voltage
dependant on type of metal in the electrode and type of electrolyte used
most batteries produce 1.5V or 2V
electric potential energy
electrical energy stored in an electrochemical cell (battery)
electric energy
moving electric energy (like through a circuit or smth) is kinetic energy
energy
the ability to do work
how electric potential energy is gained
when unlike charges are moved farther apart more electric potential energy is gained
this energy is released when the charges move towards each other and turns into kinetic energy (?)
voltage
amount of electric potential energy per coulomb of charge (yeah idk)
volt
unit of measurement for voltage
voltmeter
measures voltage between two locations of charge separation
actual electric potential energy
product of voltage and amount of charge
energy = voltage * charge
electric potential difference
voltage (idk)
