### Electricity

electrons transferred from one place to another

### conductor

allows electrons 2 flow freely

### insulator

inhibits the flow of electrons

### AC DC

2 types of electricity (electron flow)

DC stands for

AC stands for

### R E P I

units of measurements are

uom R stands for

uom E stands for

uom P stands for

uom I stands for

### transformer

voltage must be reduced for us to use our electrical needs

### voltage

(blank) must be reduced by means of transformers to a more useable level for most of our electrical needs

### Ohms Law

I=E/R amperage=voltage/resistance

### rate of flow

electrical potential/ resistance

### law of charges

like charges repel unlike charges attract

E(EMF)

### Volts

pressue that causes electrons to flow

### Electrical Pressure

E=IxR rate of flow x's resistance (equation for volts)

### amperes

measures the rate of electron flow

E/R

P=IE (w-va)

### w=va

wattage=voltage x amperage

### 120

all voltage equals

### black or red

Wire Colors hot or positive pole=

WC neutral pole=

WC ground pole=

### single phase power

is generated at 60 cycles per sec.

### ohms=r

a measurement of how much resistance there is to the flow of electrons

### r=e/i

resistance=electrical pressure/rate of flow

### i=e/r

less resistance=more amperage

### resistance

wire coils vary resistance

vary the voltage

low voltage SCR

### gating principle

switches voltage on/off 120x's a second

### 48d

1/2 rack of Dimmers=

### 96d

full rack of Dimmers=

DMX 512

### Analog

AMX 192 standard analog. signal

### control boards

manual preset computers

### sources of power

battery(1200volts) generator(6000 600volts) transformer(120volts)

### NEC

National Electric Code

series parallel

### AC Sine Curve

the alternating current sine curve created by an AC generator

### 3 Phase Sine Curves

the overlapping sine curves produced by an AC generator with 3 armatures at 120 degrees to one another.

### patching

slider panels(manual) plug panels(manual) dimmer per circuit(electronic patch)

### control boards

manual preset computer

2H 1N

3H 1N

### 20 amps

how much amps is in each dimmer?

### current increases

as voltage increases

### current decreases

as resistance increases

Example:
