MOSFET vs Transistor Testing Difference Instruction : https://youtu.be/uRA0UEP4QCw subscribe share comment like
You might have seen that in order to start a high power rating induction motor, a starting technique called star-delta is used. In this video, we will understand why a star-delta starter is needed, and how it is accomplished practically with help of animation.

PCB pad circuit repair using epoxy. Using multiple angles including overhead and from both right and left angles the BEST instructor staff demonstrates plainly how to repair a PCB pad using the epoxy method. This method is per IPC 7721 4.4.1. http://www.solder.net
with Jim Williams, Staff Scientist http://video.linear.com/18?utm_source=dcdc&utm_medium=video&utm_campaign=youtube Photomultipliers (PMT), avalanche photodiodes (APD), ultrasonic transducers, capacitance microphones, radiation detectors and similar devices require high voltage, low current bias. Additionally, the high voltage must be pristinely free of noise; well under a millivolt is a common requirement with a few hundred microvolts sometimes necessary. Circuits featuring outputs from 200V to 1000V with output noise below 100µV measured in a 100MHz bandwidth are detailed in this video. Special techniques enable this performance, most notably power stages optimized to minimize high frequency harmonic content. An additional aid to achieving low noise is that load currents rarely exceed 5mA. This freedom permits output filtering methods that are usually impractical. A lab-based circuit noise measurement demonstration concludes the presentation.
Sometimes there is only so much fun to be had building circuits with electronic components - luckily there is another option. Most electronic components are extremely sensitive to over-voltage, some also to over-current. Very few however can withstand what I have in store for them. The power supply used here is 240V AC with around 5kV superimposed on it, making it easier to establish a connection and achieve maximum destruction. A similar technology is used in arc lamp igniters. Channel owned and operated by Dan the Man. www.DantheMan.weebly.com. Proudly a member of the Fullscreen community.
