Electrical Power System
To better understand how electric power is produced and transmitted to our houses, you must know some of the most important terms used in electricity.
Voltage - is the potential difference between two points
Current - is the flow of electric energy from the source through the lines
Direct Current (DC) - the flow of current is always in the same direction
Alternating Current (AC) - the current flow changes its direction periodically
Frequency - describes the number of complete cycles performed in one second
Ammeter - the flow of current passing in a given time resistance; the force which opposes and reduces the flow of electric current
Power - refers to the amount of work done by electrical energy at a given time to make a load work
