What will happen when high voltage electricity discharges into water?

Can directly electrolyze water to produce hydrogen and oxygen.

The process in which water (H2O) is electrolyzed by direct current to generate hydrogen and oxygen is called water electrolysis. When an electric current passes through water (H2O), hydrogen gas (H2) is formed by reducing the water at the cathode and oxygen (O2) is formed by oxidizing the water at the anode . The amount of hydrogen produced is approximately twice that of oxygen. Water electrolysis is the next generation method for preparing hydrogen fuel, replacing steam reforming to produce hydrogen.

High voltage (English: high voltage) refers to the electrical connection line with AC voltage of distribution lines above 1000V or DC voltage above 1500V. Low voltage AC is less than 1000 V or DC voltage is less than 1 500 V.

The safety voltage does not exceed 36 V AC and 50 V DC. AC voltage levels of 1000 kV and above in the power system are ultra-high voltage power supplies and are generally only used as large-power long-distance transmission lines, because they can reduce energy losses during the process transmission. (The voltages used in different fields are different.) Because according to the formula P=IU, in order to reduce the loss of electrical energy during transmission, the current should be reduced and the total power should remain unchanged, so it should be adapted appropriately. increased. The voltage passes through the step-down substation and finally reaches the user's home.

Compared to ordinary power supplies, high voltage electricity presents its own special risks. There are two particular situations of high voltage electric shock:one is high voltage arc electric shock. The second is an electric shock due to step voltage. Since the voltage is very high, it is easy to get electrocuted. So be careful.

Using water electrolysis to produce hydrogen is too expensive and impractical.

The water electrolysis experiment is used to study the composition of water.

If the rate of hydrogen production is too slow, you can add salt to the water to increase the conductivity of the water.

The hydrogen production speed will be faster if the voltage of the power supply is higher, but the capacity (power output) of the power supply must also be considered.
