The relevance of ESR to capacitor selection is twofold: 1) it influences the AC response of the capacitor, and 2) it imposes limits on the amount of AC current that can be permitted to flow through the capacitor due to thermal limitations. Current flow through a capacitor’s ESR results in...
First things first. WiMo is basically a simple set of motors and sensors whose main purpose is to carry around a Windows Mobile device that acts as its brain. All of the real work is done by the phone, and all of the code that does this work is available for free on WiMo's W...
from minimal to massive quantities.what is a rectifier used for- They primarily use silicon, although they can also occasionally be found in other materials with unique properties, such as gallium arsenide or germanium. If you've ever seen their symbol rectifier, it resembles...
A: The battery is charged at higher voltage, typically 14.4V for fast charging and 13.8V for float charging. The battery's plates have a certain amount of capacitance, and can hold charge like a capacitor, thus reflecting this "plate charge." There is a surprising amount of energy stored ...
a current would always flow through the loudspeaker, even when no input signal was present. That would a) be wasteful, and b) displace the cone of the loudspeaker from its rest position, even when there was no signal. The second question is why is there a capacitor (C1) between the col...
going on. The 50 ohm load is typical of high-speed anything, but optical sensors tend to saturate like a capacitor when hit with a lot of power. Since you can't see the laser's output yourself, make sure it's getting power, so scope the laser diode lead and see what that ...
Does a symbol help or hinder our thinking about a design? Symbols are important, but what if the symbol can mean several things? This can lead to problems, as we shall see. In the analog world, a triangle can represent an op amp, a comparator, or an instrumentation amplifier...

with common words is that they're used so often and broadly that they rank poorly and are frequently lost in search results. Select more relevant or industry-specific words. For example, an electronic engineer might prefer to search the wordcapacitorrather than its older, simpler term,condenser...
starting from theschematiccapture & film stack design phase. Proper stack-up design & finish assignment for ground,power, and routing can resolve numerous signal integrity, power integrity, and EMI/EMC issues. Additional uncomplicated methods consist of selecting the appropriate capacitor, computing impe...
