1. ## A short and easily comprehensible course on digital electronics!

Digital logic circuits are electronic circuits for implementing the binary logic by means of electricity. What is binary logic? I will try to give a somewhat different view on this question. This will be at the same time a short and easily comprehensible course on digital electronics basics, so if you don’t have enough time now, please bookmark this page for later. • • • • • If we stand in front of a cooling fan, then the air current is blowing/pushing us. However, an observer standing behind the fan will say that the air current is suctioning/pulling him. The blowing force is P
2. ## Power Question

Hello everyone, "The heating element of a toaster is a long wire of some metal, often the alloy nichrome, which heats up when a potential difference is applied across it. In the U.S.A., plugging a toaster into the wall outlet is equivalent to applying a 120-V potential source across it. For these problems consider a 300-W toaster connected to a wall outlet." "How could one increase the rate at which heat is produced?" A. Use a longer wire B. Use a thicker wire C. Both A and B D. None of the above Rate of heat produce brings to mind power, P=IV=I^{2}R=V^{2}/R, but all these questions are
