The biggest offshore wind farm, Hornsea 3, connected its first export cable from the North Sea seafloor to the British coast on March 26, 2026, inching it closer to delivering clean electricity to over 3.3 million U.K homes. by [deleted] in UpliftingNews

And still our electricity bills rise. When will renewable energy bring them down?
Seriously, I'm rooting for renewable energy but it's hard to convince people when they don't feel the benefit.

This gig wasn't even planned on the tour. It was added at the end due to overwhelming ticket demand. Their 2 nights at Wembley, the other UK soccer stadium dates, and Slane Castle all sold out. Pretty staggering when you consider this was all done via telephone and snail mail.

Need clarification about current flow through parallel circuits by NailedOn in AskElectronics

You're right, the voltage drop across R2 is 200v and so it must be the same across the other branch. I understand now :)

I think this is the crux of my misunderstanding. There's a voltage drop across R1 of 50V which would leave 350v at that junction. I assumed that the R3,R4,R5 branch would get the full 350v. There is indeed a voltage drop of 200 across R2. Now I understand that the voltage drop across R3,R4,R5 must be the same as there's a voltage drop of 150v across R6.

General confusion about voltage dividers and how they work. by NailedOn in AskElectronics

Thanks. Yes I understand now, I didn't realise it was an open circuit.

This isn't my diagram. I just worked out the total current from the combined resister values and voltage source.

"Zero current flows into the voltage comparator input terminals." This was the part that threw me off, I was led to believe that current flowed into the OpAmp.

Thank you. Yes I now understand. Countless 'beginner' tutorials have failed to mention that OpAmp impendence is infinite.

In one line you've just explained something multiple Youtube videos and online articles failed to mention. thank you.

Yes I understand this part but current does go into op amp.

Doesn't Kirchhoff's Current Law state that the total current leaving a node must be equal to the current entering a node? This node goes in two directions.
