5 Laws of Electrostatics

Back 1

Repulsion, Inverse Square Law, Distribution, Concentration, Movement

Front 2

Movement

Back 2

Only negative charges move along solid conductors

Front 3

Repulsion

Back 3

Attraction

Front 4

Distribution

Back 4

charges reside on external surface of conductors- This is an attempt to repel from each other

Front 5

Concentration

Back 5

The greatest concentration of charges will gather at the sharpest area of curvature

Front 6

Inverse Square Law

Back 6

Force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them

Front 7

Electrostatics

Back 7

Study of the distribution of fixed charges, or electric charges at rest

Front 8

Electrification

Back 8

Process of electron charges being added or subtracted from and object.

Front 9

Zero or ground potential

Back 9

Earth serves as infinite reservoir

Front 10

Characteristics of Electric Circuit

Back 10

flows from positive to negative poles, but electron flow is actually from negative to positive.

Front 11

What happens to the brightness of each bulb as more bulbs are added?

Back 11

provides one path for the current to flow

Front 12

Quantity of electrons flowing

Back 12

Current (I)

Front 13

Force with which they travel

Back 13

Potential difference

Front 14

Opposition to current flow

Back 14

Impedance or resistance

Front 15

Direction of travel

Back 15

AC/DC

Front 16

Conductors

Back 16

allows flow of energy, neg (-) charge will always be on the outside

Front 17

What is a series circuit?

Back 17

is one which provides a single pathway for the current to flow. If the circuit breaks, all devices using the circuit will fail.

Front 18

What are electric circuits?

Back 18

Circuits typically contain a voltage source, a wire conductor, and one or more devices which use the electrical energy.

Front 19

The flow of charges in a circuit is called current. Current (I) is measured in

Back 19

Amperes (A).

Front 20

Resistance (R)

Back 20

is the opposition to the flow of an electric current, causing the electrical energy to be converted to thermal energy or light.

Front 21

Resistance is dependent upon 4 things

Back 21

Material’s conductivity, Length, Diameter, Temperature

Front 22

The unit for measuring resistance is the

Back 22

ohm (Ω)

Front 23

conductor

Back 23

is a material which allows an electric current to pass. Metals are good conductors of electricity.

Front 24

An insulator

Back 24

is a material which does not allow an electric current to pass.

Front 25

Length

Back 25

Directly related to resistance

Front 26

Diameter

Back 26

Inversely related to resistance

Front 27

Temperature

Back 27

Directly related to resistance

Front 28

Increased atomic motion due to increased temperature

Back 28

prevents electrons from flowing freely

Front 29

DC

Back 29

Battery

Front 30

AC

Back 30

Alternating current

Front 31

Nonmetals are good insulators of electricity.

Back 31

Plastic, glass, wood, and rubber are good insulators

Front 32

electrons flow

Back 32

flow from negative (-) to positive (+)

Front 33

electric current

Back 33

flows positive (+) to negative (-)

Front 34

What is a parallel circuit?

Back 34

circuit has multiple pathways for the current to flow. If the circuit is broken the current may pass through other pathways and other devices will continue to work

Front 35

Electrical energy enters the home usually at a

Back 35

breaker box or fuse box and distributes the electricity through multiple circuits. A breaker box or fuse box is a safety feature which will open

Front 36

The metal which makes up a light bulb filament or stovetop eye has a

Back 36

high electrical resistance.
