In electricity? High voltage ,high currents. Low voltage, low currents.
They are called high tides and low tides!
Gravity for two reasons * The water moves from a higher region to a lower one (mostly for rivers) * The moons gravity causes high a low tide, this pull the water up then drop it causing the water to stir around in currents (this is mostly for oceans)
the moon's force on earth causes high tide and low tide.
Low molo.
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
Shallow areas with low or no currents and high evaporation.
Aluminum. Commonly used in light fixtures because its cheaper and can handle those low currents.
Winds are caused by differences in air pressure not currents. Air under high pressure moves toward areas of low pressure.

high and low tides
The two causes of ocean currents are wind and the rotation of the earth(etc) The wind blows which makes the currents in the water and the rotation of the earth(gravity) makes currents in the ocean currents. Luaye Sharawy
