Yea the water conducts the electricity through the stream. The best way to put out an electrical fire is with a class c extinguisher.
However, fixed water mist extinguishers ARE used on high-voltage systems, with enough clearance to avoid arcing, where the safe design is done according to NFPA 750 Standard on Water Mist Fire Protection Systems.
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.

Water and electricity generally do not mix very well. Impurities in ordinary tap water help make it a good conductor of electricity. Using a water fire extinguisher on an electrical fire will almost always present a major shock hazard and should never be considered. That being said there is a "special" type of water fire extinguisher that can be used on electrical fires, but it uses purified distilled water and a special nozzle that disperses the water in tiny beads. To be safe, unless you know what type of extinguisher you have and what it is used for, it is best to evacuate the area and call the fire department. it makes big sparks
NO!!!!! Use a Dry Chemical extinguisher
NO!!!!! Use a Dry Chemical extinguisher
Never ever even think of fighting electrical fires with water. Somebody (probably you) will likely get electrocuted.
Water conducts electricity; therefore, using water to extinguish an electrical fire can result in electrocution.
There are several categories of fire extinguishers. It depends on where the extinguisher is likely to be used and on what type of fire is to be expected. For example: a soda and water extinguisher is commonly used for general type fires. But, due to the risk of being electrocuted, a soda and water extinguisher would be dangerous to use round high voltage electrical equipment - so a carbon dioxide extinguisher would be used instead. On oil fires, a foam extinguisher would be best, as a soda water extinguisher would simply spread the area of the oil fire, and even increase the intensity of the flames, while the foam would smother the flames, cutting off the oxygen to feed the fire.
The carbon dioxide fire extinguisher can be used on electrical fires, where there is a danger of an electrical shock if a soda water extinguisher was used.
ABC, BC or C. It is often best to disconnect the electrical power and use an extinguisher appropriate for whatever type of fuel happens to be burning (A or B). Do NOT use a water-type A fire extinguisher on an energized electrical fire.
You would not want to use a pressure water extinguisher on any electrical fire due to the possibility of electricity being conducted through the water and injuring someone. A CO2, dry chemical or "clean agent" (e.g., "Halogenated") extinguisher would be a better choice for an electrical fire, knowing that dry chemical powder will make quite a mess.
Water is a conductor of electricity, using water on an electric fire may result in electric shock, so the person putting on the water might be electrocuted as would any bystanders.
