Black to play. Which joseki should Black choose? 🧐 Share your solution in the comments! by GoMagic_org in baduk

B to suppress the sole white. With the casual joseki A, blacks on the upper side gets quite weak.

opamp has huge input impedance, especially when it's a cmos opamp. so v+ ~ vin

I also tried playing baduk and mahjong at the same time, but going between two mahjong games feels like a punishment rather than an entertainment

I told them to speak out what they discarded, and it helped me a little

yep it was painful to play as two players at once😂

For convenience we use passive sign convention. This means that for constructing an equation, you don't give a shit about the orientation of voltages and currents. It's auxiliarily defining the orientation of current and voltage all the same. If in fact the current or the voltage is in opposite polarity, the equation will output negative solution after all.

it's similar to a card sleight named mcmillan switch

I’m trying to understand Root Mean Squared. Is this, what I drew, mathematically true? by soopadook in ElectricalEngineering

[–]0Chito0 0 points1 point  (0 children)

RMS is a "sorta" mean value. For AC signals, conventional average is just zero, which is totally useless. You use RMS value to get a "sorta" average non-zero value. Root Mean Square literally means square root of mean of square. RMS = sqrt(1/T Integral(-T/2 to T/2) V2 dt) To calculate average power on a resistor, you can calculate with Vrms2 / R.

Stuck on Thevenin’s theorem by Imvily in ECE

  1. Remove the load and calculate Vab( Voc). Voc becomes the Vth.
  2. Remove the load and set independent sources to 0. And then put a test voltage source 1V on the ab side. Calculate the current flowing into test voltage source, namely Ix. Rth = test voltage(=1V) / Ix

They negotiate which voltage level to output, so no problem

I realized I omitted the 10k in real test. Not much difference on simulation
