Let’s say you have just learned Ohm’s law. Now you know that voltage equals the current multiplied with the resistance. Or, V = I * R And let’s say you have used it to calculate the current going through a circuit with only a battery and a resistor. So you used this formula: I = […]

It was back in 1980… Two American guys published a book. Their names were Horowitz and Hill. This wasn’t just any book – it was «The Art of Electronics». Since then, their book has become extremely popular. And almost all electronic design engineers have a copy of it. I also have one. It’s very
Akash from Mysore, India wrote me. …he gave me a comment about my eBook «Getting Started With Electronics». AKASH: Electronics to its simplicity!!
“Which direction does the current flow?” SUPER common question. ..both among beginners and more experienced people. Or well – more experienced people usually ask me why I draw the current the “wrong” way. So, do I? Which direction does the current REALLY go? From positive to negative, or vice-versa?
“BOING!” The nail was shot into the wall. “That was definitely not safe!”, I said to my friend. He agreed. We had just connected our self-made coilgun to the 220V wall outlet. …just to test.
In the beginning there were pins that went high and low. Super easy to work with and understand. I am talking about the good old parallel and serial ports on a computer. You might remember them. You might not.
