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.
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
Alternating CURRENT can be rectified
CURRENT can be inverted
solar panels & BATTERIES
Which can be accumulated and stored.
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
