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.
Is safety equipment like fire extinguishers and fire blankets used to prevent accidents?
No, not really. Fire extinguishers and fire blankets are used to stop fires. The "accident" would have already occurred, starting the fire.
How long did it take to put the fire out?
It matters how big, or small the fire is. Small candle fires will take a couple seconds without oxygen and one with a blow! Large wild fire can take hours and even days to put out such a big fire.
When should you inspect your fire extinguishers?
You periodically check a fire extinguisher to ensure it will be ready and functional if you need it.

Would shooting a fire extinguisher put out a fire?

How to start a fire in a fire bowl?
you get paper and role it up in to balls and place at thebottom then put fire lighters and then put sticks on top then throw some coal on and light from under the paper.
Or, if you don't want to use things that you don't need to, the easiest way to do it is to build a little structure. Get some small twigs and sticks and such, and build a little square structure like the way you would with Lincoln Logs-alternating levels of parallel sticks. Then, you need something to ignite the sticks. Paper will work, but so will dry leaves. Unless you want to get your spark from flint, a lighter will work fine. The leaves or paper will burn hot and quickly, setting fire to the sticks. From there, you want to add progressively larger pieces of wood, trying to keep the original structure you started with.

Most extinguishers have a pressure gauge which has a Red Zone marked for full pressure. Just look to see if the needle indicated pressure at near the Full mark.

Fire is a chain reaction of fuel combining with oxygen when there is enough heat to continue burning. The actual "fire" is taking place only at the surface of the fuel, i.e., the "base" of the fire. Spraying fire extinguisher chemicals or water into the smoke or flames is not as effective as aiming directly at the source of the fire.
