electricity

Matter

As anything that has mass and volume

Element

Substance that cant reduced to a simpler form by chemical means

Compound

chemical combination of two or more elements

Atoms consists of

Protons, neutrons, electrons

Elements are substances composed of…

The same atoms with specific properties

Kinetic theory

Particles are always moving

Voltage

A variable that is determined between two points, push of electron flow in a conductor

How it vvoltage measured in

Volts

Current

The amount of electron flow, measurement of a rate at which a charge flows

Resistance in a conductor

What is being forced the opposite way

How is current made

When electrons are in motion

Ohm’s law

To find resistance

Ohms law says

If volt is higher, current must be higher, and resistance be lower

Resistance of a conductor

-materials offering a resistance to current flow mdiway between the bet condition and poorest conductors (insulators) are soemtimes referred to as “semiconductors” and find their greatest application

Types of resistors

Circuit consists of

Battery, pathway, end result

Discontinuity

A purposeful gate to control electron flow

Conventional flow

• to - flow of electron pathway

Electron flow theory

- to + flow of electrons

Diode

Allows electrons to flow in one way only

Diode works mostly with what flow

Conventional flow

Current limiter

Limits electric current that flow through wires to protect circuit

How to find resister

Color code, mulitmeter

What is the 1st band color in a resister band mean

The first digit (100s)

2nd band color

2nd digit

3rd band color

Multiplier

4th color band

Tolerance percentage

AWG stands for

American wire gauge

A 40 AWG is ___ compared to a 18AWG

Smaller

How to identify where a wire belongs where

The number based on wiring diagram

Wires smaller than a size 20 AWG are provided with

Additional clamps to be grouped w other wires

Wires smaller than size 20 should NOT

Be used w hella vibration, bending, disconnection

to find I (AMPS)

E/R

Factors affecting resistance

Conductor type,metallic conductor resistance, length, temp.

Fized resistors have built what specific feature

Built To oppose current

List main methods in making a resistor

Resistance value, dissipation of heat

Resistors turn energy into to do what

into heat in ordr to remove it
