Can a resistor supply power
WebApr 24, 2024 · The SMPS can also be more compact than a similarly rated linear AC-DC supply, as the high frequency transformer and filter/reservoir capacitors are much smaller. The main drawback for the SMPS is that it must have a minimum load. No-load conditions can damage the supply. To avoid this condition, designers often use a power resistor … WebMay 10, 2024 · Voltage divider resistors are also used in applications such as automatic defibrillators to monitor the high voltage supply used to charge the storage capacitor and …

If using an oscilloscope for this sort of troubleshooting, it should be a hand-held, battery-powered instrument isolated from ground, at least at the outset. The reason is there may be …
Web74HC9114D - The 74HC9114; 74HCT9114 is a 9-bit inverter with Schmitt trigger inputs and open drain outputs. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals. http://www.qrg.northwestern.edu/projects/vss/docs/thermal/3-whats-a-resistor.html
