1
Electricity is most commonly defined as the movement
of electrons from a negatively charged location to a positively charged location
2
ELECTRICAL TERMS VOLTS aka ELECTROMOTIVE FORCE (EMF), POTENTIAL
I / R VOLTS P I / E aka ELECTROMOTIVE FORCE (EMF), POTENTIAL CAN BE COMPARED TO THE PRESSURE IN A WATER LINE
3
ELECTRICAL TERMS AMPERES aka AMPS, CURRENT CAN BE COMPARED TO
I / R AMPERES P I / E aka AMPS, CURRENT CAN BE COMPARED TO THE FLOW RATE IN A WATER LINE
4
THE TOTAL AMOUNT OF ELECTRICITY USED OR AVAILABLE
ELECTRICAL TERMS E I / R WATTS P I / E aka POWER THE TOTAL AMOUNT OF ELECTRICITY USED OR AVAILABLE VOLTS X AMPS = WATTS
5
MOST ELECTRICITY USED IS AC
ALTERNATING CURRENT MOST ELECTRICITY USED IS AC CURRENT FLOWS FIRST ONE WAY, THEN THE OTHER
6
ALTERNATING CURRENT POSITIVE HALF CYCLE NEGATIVE HALF CYCLE
7
ALTERNATING CURRENT 1\60 SECOND 1 HERTZ 1 CYCLE FREQUENCY
8
ALTERNATING CURRENT PRODUCED BY: POWER PLANTS GENERATORS ALTERNATORS
DYNAMOS

GROUNDING provides a path to earth for lightning
AC POWER DISTRIBUTION SAFETY ! GROUNDING provides a path to earth for lightning

ELECTRICAL POWER DISTRIBUTION
SAFETY ! Bonding Wire BONDING provides an alternate path to neutral

The Power Distribution System
13
DIRECT CURRENT CURRENT FLOWS ALWAYS IN THE SAME DIRECTION
14
DIRECT CURRENT PRODUCED BY: BATTERIES DISSIMILAR METALS RECTIFIED AC
LIGHTNING LEMONS STATIC EELS

HEAT LIGHT MOTION Voltage Drop & Resistance
Since energy can not be created or destroyed, the electrical energy (voltage) that is “LOST” or “DROPPED” in a circuit is changed to: HEAT LIGHT MOTION Or sometimes a combination of all three.
23
RESISTANCE & VOLTAGE DROP
24
HIGH RESISTANCE = LOW CURRENT / HIGH VOLTAGE DROP

Most wind turbines, large or small, generate three phase AC power. This is the same type of electricity produced in your car alternator or a municipal power plant.
