There is no absolute conductor in the world, conductors and insulators are relative terms. Additionally, water is an insulator, and water containing ions is a conductor (except h+ and oh-). Rainwater is formed by condensation of water vapor that evaporates from the ground, so we can consider that there are no other ions, so it will not be transmitted to lightning.
What is the calibration current? Is water conductive?
It is dangerous to use pure water, but ordinary water contains ions, so they can conduct. electricity. (For example, the tap water or well water we drink contains many substances. Just like sometimes hard water or soft water is judged based on sodium and potassium content.) simple words, if the wires are on fire and water is used to put out the fire, then Just like when a person pulls a wire directly to electrify, the purpose of not using wateris to prevent people from being injured by electricity (not to mention special circumstances).
Is water conductive?
Calibrated current means the operating current should not be higher than this, it can be lower than this, but generally it cannot exceed twice the calibrated current.
What we usually call "water" actually refers to natural water, which contains impurities and traces of Na+, K+ and other ions, i.e. There are ions that can move freely. So it's a driver.

Analysis:
Pure water cannot be qualified as conductive, but it can also be conductive, but its conductivity is very low. So of course, tap water is more conductive. Water from the water plant is only disinfected, sterilized and cleaned of sediment andorganic sediments. It cannot eliminate anions and cations. , organic and inorganic ions in water. Small molecules that do not precipitate. Pure water itself is an extremely weak electrolyte, a water molecule is ionized and substances that cannot be. ionized It cannot conduct electricity. To do a conductivity experiment, three conditions must be met: (1) a conductive battery, preferably a U-shaped tube (2) two electrodes and an outer wire plus an ammeter (3) a DC power supply. Put in the conductive solution. Pour it into a conductive battery, connect two electrodes in parallel and connect it to the power supply. As long as you see the pointer in the ammeter oscillating, this proves that the solution can conduct electricity. use pure water to test, you need to add some substances to improve the conductivity. For example, sodium hydroxide,etc. The concept of conductor that we are talking about here cannot be confused with the concept of metallic conductivity. Electrolytes can conduct electricity, no matter how strong they are! or they are weak. The conductivity of metals is the directional flow of electrons, while the conductivity of electrolyte solutions is the bidirectional flow of ions. Therefore, the concept of conductivity has different meanings wherever it is used. The conductor cannot be used for electrolytes. Therefore, conductivity and conductor are two different concepts.
