Q: The percent impedance of a transformer is also the voltage drop of the transformer at full load. What is the voltage drop of a transformer at various other load levels, i.e. 25%, 50%, 75% or in ...

How do you deliver constant power when the load impedance isn't constant? That problem arises, for example, in trying to maintain a warm LCD display on an outdoor gas pump in cold climates. As the ...

[Ralph] is excited about impedance matching, and why not? It is important to match the source and load impedance to get the most power out of a circuit. He’s got a whole series of videos about it. The ...

Guest columnist Subhodeep Ghosh of Cypress Semiconductor looks into the stability issues affecting the usefulness of powerline communications as a networking technology. Powerline communications (PLC) ...

Most voltage references are designed to drive a low to moderate amount of current, typically less than 10mA. Drawing even moderate current levels– for example, 10mA — can result in degraded ...

Impedance mismatch in a circuit results in energy being reflected back to the source, reducing the amount of power available to the load and possibly causing damage to the power source. Matching the ...
