For example, if a circuit is created through the human body, why does a high-frequency current not flow through the body, but rather on the body or over the skin? Why does the current not reach deep into the body due to the high frequency, what prevents it from flowing through the body and how…
Electrician or road maintenance worker. The guy is retraining to become a road maintenance worker because he thinks the pay as a road maintenance worker is better than that of an electrician!? Is there anything to this?
Hello, I have a question. I will soon be finishing my apprenticeship and wanted to ask how much net and gross I can expect in this job?
So, I'm currently learning how to calculate conductor cross-sections. While I've been learning, I've discovered two different ways to calculate this. The first way is with a formula: Alternating current:A=(2 × L × I x cos(φ)) ÷ κ x ΔU Three-phase current: A=(√3 × L × I x cos(φ)) ÷ κ x ΔU The second…
So if you have already completed training as an electrician.
I started my apprenticeship as an electrician on September 2nd and have had back pain every day since then. Is this normal at the beginning or am I doing something wrong?
Hello, I'll be renting a car (compact station wagon, Peugeot 308 or similar, diesel/gasoline unknown, definitely not an electric car). I assume it will have a fairly new battery. I want to connect a small freezer to it overnight (which operates according to the Peltier effect, meaning it's just a fan). It consumes 48 watts…
I've already asked two similar questions here, but since I'm a few steps further along, I'd like to ask again. So I have a DT 50 MX built in 1989. This is in perfect condition – except for the fact that the charging voltage is too low. The Yamaha has 6 volts. The battery is…
Hey, my training to become a master craftsman starts in September. The first exam starts in just a month. This is a bit worrying. Can someone explain to me how you managed it and what the exam was like?
I wanted to apply for an apprenticeship as an electrician, and I thought it would be helpful if I included terms that would be covered in the training in my cover letter. Are there any terms I could already know before starting the apprenticeship to simply demonstrate my interest in electrical work?
