Things to keep in mind when learning a new field

I recently started studying for my Class 2 Electrician's License.

Once I obtain the license, I will be able to:

  • Indoor wiring work for homes, small stores, and offices (wiring routes, cable connections, etc.)
  • Installing and replacing lighting fixtures, and installing, expanding, and replacing outlets and switches
  • Installing and wiring distribution boards (low-voltage side), and connecting devices such as air conditioners, ventilation fans, and intercoms.

I started studying because I wanted to understand how the electricity we use every day is allocated and wired to each household.
(A license would be one of a learning goal, and I could do DIY too.)

I bought a book and started studying.

The topics Ohm's Law and Fleming's Law reminded me of my student days.

However, there were many parts of the content that I didn't understand.

After reading through it once, I found:

  • Parts I could understand (I could solve the example problems immediately)
  • I could understand the concept, but I couldn't remember the formulas
  • There were parts that I didn't understand at all, or couldn't imagine.

At this point, I skip over any parts I don't understand.

  • What I understand
  • What I don't understand

First, it's necessary to start by understanding my current situation.

It's also important to read the book all the way through to get a grasp of the big picture.

  • The first time, quickly grasp the current situation.
  • From the second time onwards, slowly deepen understanding and solidify knowledge.
