electrons transferred from one place to another
allows electrons 2 flow freely
inhibits the flow of electrons
2 types of electricity (electron flow)
Direct Current (batteries)
DC stands for
Alternating Current (generators)
AC stands for
R E P I
units of measurements are
uom R stands for
voltage must be reduced for us to use our electrical needs
(blank) must be reduced by means of transformers to a more useable level for most of our electrical needs
rate of flow
electrical potential/ resistance
law of charges
like charges repel unlike charges attract
pressue that causes electrons to flow
E=IxR rate of flow x's resistance (equation for volts)
measures the rate of electron flow
wattage=voltage x amperage
black or red
Wire Colors hot or positive pole=
single phase power
is generated at 60 cycles per sec.
a measurement of how much resistance there is to the flow of electrons
resistance=electrical pressure/rate of flow
less resistance=more amperage
wire coils vary resistance
vary the voltage
low voltage SCR
switches voltage on/off 120x's a second
full rack of Dimmers=
AMX 192 standard analog. signal
manual preset computers
sources of power
battery(1200volts) generator(6000 600volts) transformer(120volts)
National Electric Code
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.
slider panels(manual) plug panels(manual) dimmer per circuit(electronic patch)
manual preset computer
how much amps is in each dimmer?
as voltage increases
as resistance increases
