Static electricity...
Generally considered a nuisance... can cause serious damage to electronic equipment... (it is STORED power)
Thunder & lightening are
STATIC electricity...
Wiki definition included (below)
For commercially available ELECTRICITY...
(usa) "currents" ... All electricity functions because of a
DIFFERENCE in potential. When you start adding wires then you are harnessing that potential DIFFERENCE into usable energy.
Direct current &
Alternating current... Generally referred to as "AC" & "DC"
Most all of the
power grid you are looking at on power poles around your community... have "AC" flowing on the power wires
good for powering residential housing and commercial power applications
Immediately below those wires ... The phone wires
have to run about 10 feet below the "AC" wires...
Phone systems run on "DC" because it is quiet
(communications systems).
Alternating CURRENT can be
rectified into
Direct...
and
Direct CURRENT can be
inverted into
Alternating.
Generators, solar panels & BATTERIES
output
DC
Which can be accumulated and
stored.
Alternators output AC... and because AC is less susceptible to magnetic interference... it can travel great distances with very little loss.
Very interesting topic for further research ... and the principals of both... as argued by no less than Nicola Tesla & Thomas Edison.
Hope this helps
