This video teaches viewers how to identify failed electrolytic capacitors, which are common components that can cause problems in electronic devices. The video covers three failure cases, ranging from easily identifiable bulges to more subtle issues that require an LCR meter or multimeter to detect. The video also provides tips on how to identify capacitors that are likely to fail due to environmental factors.
32226 2 года назад 3:43This video demonstrates how to diagnose and repair a capacitor start motor. The video focuses on a common issue where the capacitor fails, causing the motor to hum and not start. The presenter shows how to test the capacitor using a multimeter and how to replace it with a new one.
229041 5 лет назад 5:22This video demonstrates how to identify shorted ceramic capacitors without using a power supply. The presenter explains that shorted capacitors act like wires, allowing power to flow directly to ground. They then show how to visually inspect capacitors for signs of damage, such as cracks or discoloration, which can indicate a short.
112824 3 года назад 11:13This video explores the possibility of measuring capacitance without desoldering capacitors from a printed circuit board (PCB). The presenter conducts an experiment using a multimeter to measure the capacitance of various components on a PCB, comparing the results to the actual capacitance values obtained after desoldering. The experiment aims to demonstrate the limitations of measuring capacitance without desoldering and the potential for inaccurate results.
315705 9 лет назад 13:36This video demonstrates three ways to test a start or run capacitor for single-phase electric motors. The first method is the correct way to test the capacitor using a meter with a specific symbol. The second method is a dangerous test that should only be used in emergencies. The third method is a pointless test that does not provide useful information.
