Students are also taught to use electrical diagrams to understand basic principles of power and electricity. An electrical diagram's benefit lies in the fact that it acts as a universal guide about circuit. It is particularly practical for electrical maintenance professionals who need to understand ...
《DC Electrical Circuit Analysis: A Practical Approach》(James M. Fiore)是一本介绍直流电路分析理论和实践应用的教材。下面是我对这本书的书评: 1. 图书内容梗概 本书从科学和工程符号以及公制单位开始,讨论了科学方法,即我们整个调查和技术体系的基础。接下来,介绍了电荷、电流、能量、功率和电压等基本概念和...
Whenever electrical wiring in a building has too much current flowing through it, these simple machines cut the power until somebody can fix the problem. Without circuit breakers (or fuses), household electricity would be impractical because of the potential for fires and other mayhem resulting ...
If you need to build a circuit, either breadboard or PCB (printed circuit board), then you’ll want to use a tool that can link a schematic to a physical layout. Fritzing is a great choice for this—it’s very easy to learn, and can handle both simple PCB layouts, as well as brea...

If gain is required in the circuit, it cannot be added to the filter itself. The filter can potentially have a high output impedance. Since the resistor value is typically large, to keep the capacitors a reasonable value, the next stage device can see a significant source impedance. An op...
C1 is the input capacitor. C2 is the output capacitor. They are basic electronic components that we use very often and are very familiar with. They store electrical energy and release it in the same polarity. S1 is a switch; in the real circuit, we will be using a transistor or MOSFET...
Added internal circuit breaker specifications to section "Technical Specifications." 06 2015-06-26 Updated the software version. 05 2014-09-26 Added the feature of four UPS paralleling and battery monitor unit (BMU). 04 2014-07-16 Updated the safety information. 03 2014-01-20 Upda...
The effect is fantastically useful for these applications, but can also be problematic when it results in unintended coupling of mechanical signals into an electrical circuit, becoming a noise source or worse yet, an unintended feedback path. The transduction mechanism is also bi-directional; ...
Despite its critical nature in high-speed circuitry, printed-circuit-board (PCB) layout is often one of the last steps in the design process. There are many aspects to high-speed PCB layout; volumes have been written on the subject. This article addresses high-speed layout from a practical ...
