It is relatively difficult for second-level electricians to write papers. Thesis is one of the important indexes to evaluate students' comprehensive ability, which requires students to have theoretical and practical abilities. The thesis of the second-level electrician usually requires students to carry out practical projects independently and analyze and summarize them in combination with relevant theories. This requires students to have solid professional knowledge and practical experience, and can better use the theoretical knowledge they have learned to solve practical problems.

In addition, the difficulty of the second-level electrician's thesis is also related to the students' professional background and personal ability. For students, it may be easier if they have in-depth understanding and research on electrical engineering and have some practical experience. But for beginners or students who don't know much about electricity, the paper will be more difficult and need to spend more time and energy to study and practice.

To sum up, the difficulty of the second-level electrician's thesis is relatively large, but the difficulty will vary according to the students' own professional background and ability.
