Flashcards in vocabulary Deck (19):
1

switch

opens and closes a circuit

2

electric charge

a fundamental property of matter; there are two types- positive(+) and negative (-)

3

open circuit

a circuit in which there is a break in the wire so that current cannot flow

4

closed circuit

a circuit in which the switch is turned to the "on" position causing there to be no breaks in the circuit

5

electrostatic force

the force that exists between electric charges

6

coulombs law

as 2 charged objects get closer, the force between them increases

7

coulomb

the unit for electrical charge

8

current

the quantity that refers to the rate of flow of electric charges

9

insulator

something that blocks the flow of electric current

10

conductor

a metal; a material that energy can easily flow through

11

voltage

the amount of potential energy that each unit of electrical charge has; 1 volt= 1 joule/ 1 coulomb

12

electrical conductivity

the ability of a material to conduct electricity

13

battery

a device that uses chemical energy to move electrical charges

14

resistance

the measure of an objects ability to conduct current

15

ohms law

describes the mathematical relationships present in most circuits

16

series circuit

a circuit in which the current only has one path

17

parallel circuit

a circuit in which the current can take more than one path

18

short circuit

a branch in a circuit with zero/very low resistance

19

circuit diagram

the diagrammatic representation of an electric current
