19 Terms

1

electrochemical cells

convert chemical energy into electrical energy

New cards
2

battery

electrochemical cell or multiple electrochemical cells connected together

New cards
3

terminals

end points of a battery where connections are made

New cards
4

negative terminal

end where electrons accumulate

New cards
5

positive terminal

end that has lost electrons

New cards
6

electrodes

battery terminals and the rod that connects them

New cards
7

electrolyte

conductive substance surrounding the electrode

New cards
8

dry cell

electrolyte is a moist paste

New cards
9

wet cell

electrolyte is a liquid

New cards
10

amount of voltage

dependant on type of metal in the electrode and type of electrolyte used

most batteries produce 1.5V or 2V

New cards
11

electric potential energy

electrical energy stored in an electrochemical cell (battery)

New cards
12

electric energy

moving electric energy (like through a circuit or smth) is kinetic energy

New cards
13

energy

the ability to do work

New cards
14

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 (?)

New cards
15

voltage

amount of electric potential energy per coulomb of charge (yeah idk)

New cards
16

volt

unit of measurement for voltage

New cards
17

voltmeter

measures voltage between two locations of charge separation

New cards
18

actual electric potential energy

product of voltage and amount of charge

energy = voltage * charge

New cards
19

electric potential difference

voltage (idk)

New cards
robot
