Switching between series and parallel connection of batteries …
May 22, 2023 · Of course, if one of those interlocks sticks, big bang boom... I suppose SP1 and SS could be replaced by one "pole" of a DPDT switch, and SP2 replaced by the other pole. But I'm assuming you're dealing with pretty big DC power here, and you seem price sensitive - a DC-rated transfer switch rated for interrupting big power can be costly.
How different are 8-bit microcontrollers from 32-bit …
Apr 17, 2014 · On the other hand, there are times when code will have to "big-bang" a lot of port manipulations, and the ability to do such things with a single instruction can prove quite valuable. On the flip side, 32-bit controllers are invariably designed to efficiently access many kinds of data structures which can be stored in memory.
batteries - Using capacitors as a battery back-up - Electrical ...
Apr 6, 2022 · Fuses F1 and F2 are important. F1 protects the capacitor bank from destructive discharge (a.k.a. a big bang) should the DC link become shorted. F2 protects RLY1 and the associated wiring, since it wouldn't be rated for the full output current of 10-15A. The unsafe voltage on C2 is indicated in an energy-saving fashion by two indicators: X1 and X2.
current - So which direction do electrons really flow? - Electrical ...
Jul 24, 2018 · As I understand it, electrons (which are negatively charged) flow towards positive. As a convention, we say that current flows from positive to negative. Is this to say that what you connect the
What is back EMF? - Electrical Engineering Stack Exchange
Apr 27, 2021 · A big voltage potential, called Back EMF (ElectroMagnetic Force) will let the flowing current to continue to flow, by ionizing the nearby air to become sort of a electricity conductor (actually a poor conductor, or high resistance), and the otherwise no where to go current would happily go through.
Why do my speakers make a noise when my cell phone gets a call?
Aug 30, 2012 · From the foreword: The GSM 1800 MHz (PCN) element was added a few years later when the UK's DTI was at the leading edge of telecommunications liberalisation and I propelled it to be the first credible entity to set out the vision of the personal mobile phone as a consumer product (‘Phones on the Move’) and put forward the conditions to make it happen.
High voltage capacitor discharge tool - Electrical Engineering …
Aug 23, 2021 · Just remember, shorting a large capacitor unleashes a lot of power and give off sparks and huge bang. PS: i was reluctant to present this as a answer as opposed to a comment because i dont want a quick browser to think this is the way to go. Again, be very careful!
What is bit-banding? - Electrical Engineering Stack Exchange
Mar 4, 2012 · The ARM info center refers to bit-banding in their Cortex-M3 and -M4 documentation, compiler docs, and a few other places, like Home > Programmers Model > Bit-banding.
What happens when a ceramic bypass or decoupling capacitor …
Nov 13, 2019 · Too much voltage can cause the dielectric (insulating) layers to break through and become short circuits. Too much voltage can also cause the capacitor to flex, resulting in a stress crack. Then you get the same result as above. The capacitor becomes more like a resistor, or shorts out entirely - bang or burn. Neither failure mode is usually a ...
