you should use dry powder extinguisher
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.
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
Because it is dangerous to use water to extinguish a fire involving electrical equipment. The water can conduct electricity to the person fighting the fire and electrocute them. One should use dry powder on electrical fires.
The function is to fight a fire which will either extinguish the fire or to fight it long enough to allow safe passage from the location - The main and most important is to use the correct extinguisher and to leave the area if the extinguisher is not impacting on the fire.
You should use a fire extinguisher when a fire is small and contained, such as a small grease fire on a stove or a trash bin fire. It is important to remember that you should only attempt to use a fire extinguisher if you have been trained in its proper use and if it is safe to do so. If the fire is large or spreading quickly, evacuate and call emergency services.

The best location to put the fire extinguisher is inside the lab, near the door so that if the fire extinguisher is used but does not put out the fire, you can still escape via the door. Never allow the fire to come between you and a safe means of escape.
Each one has its advantages and drawbacks, depending upon circumstances. For example, dry powder residue may be very difficult to clean from the area surrounding its use (assuming it put the fire out), but it is often a general-purpose extinguishing agent that can be used on several types of fires. A foam extinguisher may contain water that would not be safe near energized electrical fires (unlike dry chemical powders), but may cover a larger area of fire with a smothering blanket of foam.
Our fire extinguisher training sessions take students through the different classes of fire, proper selection of fire extinguishers, how to effectively use a fire extinguisher, and when it is safe to fight a fire so that everyone knows how to best respond in an incident. Then, we'll give participants hands on experience with a live fire simulator that's controlled by the instructor.
