r/MechanicalKeyboards on Reddit: When can an already soldered choc switch be opened without
I think it''s relatively noob friendly, this was the first time I''d ever soldered anything myself and I didn''t think it was taking on too much. Just take your time, don''t rush, concentrate and you''ll be fine. Honestly I had to desolder my current switches and installing the millmax sockets is about 1000x easier than that. 2.
From Fertilizer to Fuel: Can ''Green'' Ammonia Be a Climate Fix?
A 2021 International Energy Agency report forecasts that to hit zero emissions by 2050, hydrogen-based fuels (including ammonia) should account for nearly 30 percent of transport fuels by 2050, up from basically zero today. That report predicts that cars will run on batteries and planes on biofuels, but ammonia will be vital for the shipping
Solved An inductor used for storing energy can be modeled as
Electrical Engineering questions and answers. An inductor used for storing energy can be modeled as a 100 mH inductance in series with a 5Omega resistance. The controlled six-pulse three-phase bridge rectifier is used for the energy storage process. Assume the inductor to be large enough to maintain a constant output dc current.
Can you store energy in an inductor and use it later?
The magnetic field which stores the energy is a function of the current through the inductor: no current, no field, no energy. You''ll need an active circuit to keep that current flowing, once you cut the current the inductor will release the magnetic field''s energy also as a current, and the inductor becomes a current source (whereas its dual,
