Does junior high school physics talk about electrician knowledge?

Junior high school physics and electricity only have the simplest basic knowledge of electricity, know basic circuit symbols, components and electricity safety knowledge, and master the laws of current, voltage and resistance in basic circuits and further contents of electric energy and electricity.

I feel that I have basically no knowledge of electricity. If you insist on finding something, then the part about home circuits and safe electricity use in the Su Ke edition may be slightly involved-it depends on the physics teacher to expand his knowledge.

When I say electrician knowledge, I mean practical engineering technology in real life, such as fault maintenance, electrical installation specifications and technology.

It is not easy to answer questions, I hope I can help the landlord.
