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:
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 =).
