Electricity is most commonly defined as the movement of electrons from a negatively charged location to a positively charged location

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

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

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

MOST ELECTRICITY USED IS AC ALTERNATING CURRENT MOST ELECTRICITY USED IS AC CURRENT FLOWS FIRST ONE WAY, THEN THE OTHER

ALTERNATING CURRENT POSITIVE HALF CYCLE NEGATIVE HALF CYCLE

ALTERNATING CURRENT 1\60 SECOND 1 HERTZ 1 CYCLE FREQUENCY

ALTERNATING CURRENT PRODUCED BY: POWER PLANTS GENERATORS ALTERNATORS DYNAMOS

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.

RESISTANCE & VOLTAGE DROP

HIGH RESISTANCE = LOW CURRENT / HIGH VOLTAGE DROP
