MIN-HYUK (CONT’D) It’s heavy so I had to bring it on my bike. KI-JUNG What’s this? Ki-Jung lifts the flap to see a UNIQUELY SHAPED STONE and a wooden display stand inside. MIN-HYUK (to Ki-Tek) When I told my grandfather I was going to see Ki-Woo, he gave me ...
What It Takes to Break a RAM with ESD (ft. Linus Tech Tips) 18:50 What’s a Circuit, Series and Parallel (ElectroBOOM101–005) 10:46 What’s AC and DC (ElectroBOOM101-003) 10:02 What’s an OSCILLOSCOPE 11:49 Why 3 Phase AC instead of Single Phase 10:57 Why Charging Pho...
One example is the need to go from single-phase 240-volt (V) to 480-V three-phase arrangement when a machine rated at 480 volts is present. The device used to do this is called a transformer. But what are "phases" in the context of electricity and why are they present in electrical...
§3. How to wire AC Voltage Regulation Module? §1. How to wire Single Phase AC Voltage Regulator? 1.1 Potentiometer Type MGR-R Series This kind of potentiometer type single phase AC voltage regulator uses a standard package (rectangle shape) with four terminals. Port1 and Port2 are output...
When testing fixed wired or 3-phase equipment, a number of safety tests can be carried out by powering the safety analyser from a normal mains supply provided this is at the same earth reference as the fixed wired equipment (single or three phase). ...
To use a multimeter to locate short circuits on a PCB, set it into continuity mode and place its probes either side of the suspected shorted circuit. If a beep sounds from your multimeter when there is continuity between them indicating shorting, use it to trace and find its source. ...
How to Connect Step-Up 3-Phase Transformers. Single-phase transformers use the ratio between the primary and secondary windings to step up the input voltage. Three-phase transformers work the same way, but they are configured differently. Instead of a pr
The large surface area of the wire mesh quickly absorbs most of the heat. This leaves less heat to be removed by the cooling fins. Next, the piston in the cooled cylinder starts to compress the gas. Heat generated by this compression is removed by the cooling fins. In the last phase ...
The other wire is the GROUND or EARTH or NEUTRAL. Sometimes the Neutral is also delivered as a wire, but let's take the case of a single ACTIVE wire. The voltage in the active wire is rising 336v HIGHER than earth then it falls to 336v LOWER than earth. It is rising and falling ...
Now, you may have noticed that almost all commercial airliners have more than one engine. But so far your training has all been undertaken on single-engine aircraft hasn't it? So now it's time to expand your experience to include flying twin-engined aircraft. Of course, having two engines...
