science circuits

parallel

type of circuit in which different loads are on separate branches

insulator

a material in which charges cannot easily move through

current

rate at which charges pass a given point

potential

energy per unit charge

the law of electric charges states:

like charges repel and opposite charges attract

bulb

a device in a circuit that uses electrical energy to do work

thermocouple

a device that converts thermal energy into electrical energy

battery

consists of several cells

circuit

a complete, closed path through which electric charges flow

resistance

the opposition to the flow of electric charge

switch

used to open and close a circuit

cell

a device that produces an electric current by converting chemical energy into electrical energy

discharge

the loss of static electricity as charges move off an object

photocell

part of a solar panel that absorbs light and converts it into electrical energy

conduction

the transfer of electrons from one object to another

induction

rearrangement of electrons on an uncharged object without direct contact with a charged object

electric force

the force between charged objects

electric power

the rate at which electrical energy works

conductor

a material in which charges can move easily

static electricity

the build up on electric charges

voltage

the difference in energy per unit charge as a charge moves between two points in the path of a circuit

series

type of circuit in which all parts are connected in a single loop
