My first Electrical Principle Lab

I am taking two modules this semester in Singapore Polytechnic, which is Digital Principle and Electrical Principle. For the former one, I used to learn it in my first year of Computer Science course. It is basically about binary logic (digital), boolean algebra, logic gates (AND, OR, NOT, NAND, NOR, flip-flop, etc). For Electrical Principle, so far I studied about basic electricity law which can be found in high school (the terminologies like voltage, current, charge, energy, resistance, etc).

My first lab session in Singapore Polytechnic started last week and the technician introduced us to basic devices which I believe are quite commonly used as electrician such as multimeter, DC power supply and resistors with color bands.

The devices can be found below:

Digital multimeter:

In short, it is quite nice session. We basically learned how to measure current, voltage, resistance, reading color bands, and using DC power supply by connecting the cables.

Looking forward to another lab session tomorrow with digital principles =).

I am currently Indonesian expatriate working in Singapore. I am currently working as security researcher in National University of Singapore. I write this blog to share to readers about my life principle on various aspects, like religion, politics, business, relationship, and technology. I am interested in alternative worldviews because I found that many things taught to us by establishments are not true and harmful. My dream is to become self-sufficient in food and energy. Hopefully, someday I can have my own fruit garden and my own power plant and able to sell my electricity to power company. I hope readers enjoy my blog.
