Lol, not sure why he didn't give the answer, since it was a simple series/parallel resistance calculation that even a first year electronics student could calculate.

 

Anyway, a quick calculation gives about 198.7 ohms and so using I=V/R, we get a current of about 0.12A (hope I haven't made any maths errors!!)

 

But I'm sure you didn't know the answer, did you Bob?

I learnt all that stuff in 1960 and 1961. Never used it since and have long forgotten how to do it.

hi, since i have joined this forum i have seen many posters refer to me as bob. i have no idea who bob is and i dont know abyone called bob. my name is colin neville, 68 years old from dorset, I attended poole high school and graduated from dorset college majoring in electronics. whoever this bob character is it isn’t me, so please stop calling me that. thank you.

BOB , I got your message. I promise not to refer to you as Bob ok. Bob ??

Hey Bob.

Slow down. Learn to count. Start using capitals at the start of each sentence. And make your stories at least slightly believable.

what the hell is going on here and who the hell is this bob!!! my god, if i would have known this is what would happen i woudlnt have signed up. i am not bob, never have been and never will be. i am colin and ive been living in thailand for 5 years. i have some issues that need sorting out and i thought this would be a good place to air them. perhaps i was wrong?

Hang around "georgiageorgia" will have a session with ya!

My guess is 450 Ohms.  No idea whether I am correct as the last time I did physics was 49 years ago.

No problem, but completely wrong lol 🙂 .  Resistors in parallel always have a combined value that is less than the value of the lowest-value resistor. So 100 and 250 ohms in parallel will have a total value less than 100 ohms.

 

Anyway, this is not a Physics class! Perhaps Bob (I mean Barboy) could remind us of some of the topics from his BSEE course, since his lecturers seem to have forgotten to teach basic resistor circuit theory 🙂

OK,  Bob, whatever you say.

 

But... if what you wrote above is actually true, then it was truly awful idea to post this...

Congratulations on graduating with a major in electronics.  Please tell me the total resistance of this circuit and the current:

If he is from Dorset, then electronics is limited to:

red to red and black to black,

switch it on and stand well back!

For anyone wanting to have a go: "Ohms law states that the current in any electrical circuit is directly proportional to the voltage and inversely proportional to the resistance. Providing the temperature remains constant." 

At least it was in the early 1960s, Keir Starmer's probably gone and changed it now.

Forum owners must love Bob. Comes back as BarBoy, starts 2 threads which have 223 replies and 7.7k views. 

 

And all he's said is what Bob has said hundreds of times in that he gets drunk and constantly cheats on his wife with Ladyboys, which he doesnt think is gay. Real upstanding bloke 😀

If you're looking for a Rolex, I know a guy who knows a guy.

If you are 68 years old, you were born in 1956. I can see why you would forget, being 4 or 5 years old. I think you are bob or boob.

I’ve resisted having a go….too tired now, need to recharge my batteries….but I’ll have a go tomorrow…….spark up a few brain cells.

Who are you kidding? You have pm'd @Crossy and he hasn't answered yet.

Also a gold band was within 5% tolerance, silver within 10% and no colour was within 20% tolerance. Totally useless nowadays.

Bill, as an 'old skool' shortwave radio ham, I use the resistor colour code almost everyday 🙂

I haven't been here long, but even I recognized Bobs standard two sentence reply, merely without his customary signature of a simple bob🤣

Don't cheat on your wife old bean and guilt wont be an issue. Or, divorce and it's also no longer an issue🤣
