Hello everyone, While I was chopping candied orange peel with my hand mixer for a while, the inside of the mixer suddenly lit up and began to smell horribly. It also started emitting smoke. It then stopped working. I opened it and looked inside. Suspecting the capacitor was the source of the problem, I removed…
Good evening, I understand what direct current and alternating current are. I know that alternating current involves a periodic (regularly repeating) reversal of voltage, changing from positive to negative and back again. This causes the electrons in the conductor to move back and forth. But how can electrical devices be powered if the electrons only…
Good day, I have a CPI GTR 50 water-cooled (2-stroke) from 2004 and registered in 2006. Unfortunately, the battery discharges while riding, and the scooter shuts off. I just removed the battery and connected it to the charger. Since the battery is only a month old, I don't think that's the problem. Does anyone know…
Hello, I have my physics assignment back and I don't understand what our teacher wants with this task. With alternating current, the positive and negative poles are constantly being reversed. This creates a sine wave that goes both positive and negative. (Figure 2) If a rectifier is then installed, only the positive curve is always…
Hello! I'm currently tinkering with my model railway and trying to acquire some of the knowledge I need for it. I have absolutely no idea, and I'm not really connected either… I'm planning to retrofit some lighting. For example, for the lanterns or LEDs on the control panel. For that, I need direct current. However,…
Hello everyone, I'm back again on the topic of "electrics in caravans". Today I retrofitted a Titan refrigerator fan and connected it to the 12 V junction box in the kitchen cupboard using Wago terminals. Now I've read in retrospect that the manufacturer recommends connecting a rectifier. :-\ Since I went to the junction box…
Hello, I tried to program a full-bridge rectifier (pictured). Is the way I did it correct?
Hello dear community, I have a 400A MIG welder. I noticed that three diodes in the rectifier are defective. They use Siemens E1120 and E1220 anodes and cathodes. Since I can't find them anywhere, and I found an offer for Siemens E1140 and E1240 from an old stock, I'm toying with the idea of installing…
How did people generate direct current in old chargers from the 1940s and 1950s for car batteries? Were diodes already available back then? Can you still buy them today?
Hello, our physics homework over the holidays is to create a circuit that generates the smoothest possible DC voltage from the 230V mains voltage, in the range of 20-40V. We're also supposed to write a text briefly explaining the circuit, which I'll do later. Weißlich asks why the resistor and the coil are there; these…
Hello everyone! I've been given physics homework, but I have absolutely no idea how to do it. I've already done a lot of research and looked it up online, but I just can't seem to get it right. Can someone help? The problem is just too difficult for me… Thanks in advance! LG
