It is the Class C fires that invlove electrically energized equipments, and they are suppressed using CO2 extinguishers or dry chemical extinguishers. Certainly the use of water or water-based extinguishers or other water-based suppression equipment is not to be considered.
A fire extinguisher with a class "C" rating. It has a blue circle with a "C" in it.
co2 powder extinguisher
A class "C" fire extinguisher
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.

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.
What 'type' the fire is. The right extinguisher must be used for any fire. Or, more importantly - it can be very dangerous to use the wrong type of extinguisher, such as one with water should never be used on an electrical fire.
you should use dry powder extinguisher
liquid and electrical fires.
Fire extinguishers are not usually classified by color. They are classified by letters A, B, C, D and K. Electrical fires are a type C fire and require either a class C extinguisher or a ABC (known as a multi purpose) extinguisher.
type B
A CO2 fire extinguisher will work on flammable liquid and electrical fires only. If used on any other type of fire they will just give it more oxygen and it will spread.
A classroom would generally contain only "ordinary combustibles", so a type A fire extinguisher would be appropriate. In a chemistry laboratory, cooking class, automobile engines, electrical or welding class, different rules would dictate the type, placement and number of required fire extinguishers, typically Type ABC (multi-class).
powder or foam :)
An electrical fire is a class B fire. If possible, the electricity causing the fire should be shut off. The most common fire extinguisher for this type of fire is an ABC dry chemical extinguisher. Class C can be used in a pinch, but a class A should NEVER be used if the electricity is still present in the fire.
