... Energy of kick back voltage is consumed by TR1(or TR2). When ZD1 is in operation, Collector voltage is sum of Vbe and ZD1. Therefore, breakdown voltage of ZD1 must be lower than that of TR1. 2) By insertion of ZD2 (zenner diode connected between Collector and Emitter of TR1) Energy of kick back volt ...

... As electrons collect on one plate of the capacitor they repel any more electrons moving on to the plate. This repulsion force must be overcome for more electrons to collect on the plate so “work has to be done”. This “Work Done” is the energy stored in the capacitor ….. E = ½ Q V …. Area under Q ...

... current IC is used to control the intensity and power of SMD LED Tube light. B. Working and calculation Forward voltage of SMD led is 3.3V approximately. Lumens range is from 180 to 200 so average lumens is 190 and we want 8 SMD led to mount on strip SMD led PCB so total lumens is 190*8=1520 lumens ...

... If anything heats up too fast, it won't have enough time to release its heat to its environment, so it may expand and crack, or melt. In our case, the resistor will could all three things: expand, crack, and melt. We will stop short of the melting stage. The larger a given resistor is, the more ther ...

Josephson voltage standard
A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement, is the basis for voltage standards around the World.
