I had McAffee install itself on my Win10 PC as a byproduct. I removed it with a program called REVO uninstaller and I was surprised to find the HUGE number of files that McAffee dumps onto a PC. It seems to have its hooks into everything. Managed to finally clear it all out. Even using McAffee...
Oh, sorry for the misunderstanding. The value for Ro is given by the equation
Ro = SQRT(R1 x R2+(R1 x R1) / 4) = 60 so in the first eqn. Ro actually equals 60.
sorry if it wasnt too clear . my bad. does that help?
sorry no diagrams with this problem.
The problem is to find the values of R1 and R2. I have tried manipulating the known answers to find the correct algorithm(big word that) but cannot find the correct method. I suspect it turns into some kind of quadratic but its been so long ago since I played...
Hi Eric, Fixed your problem yet. I suspect you need a better understanding of the issue. If your coil resistance is 0.5 Ohm as you quote, when you connect your supply set to 12 volts the current will be 24 amps. This will no doubt cause overheating and a very low magnetic force ( depends how...
Greetings, fellow travelers.
I gave been digging into some of my old (1970s) Electronic maths textbooks and for my amusement and time wasting refreshing some old knowledge. Have got through a fair but but have to keep coming back to this problem.
I do have the answers but I cannot regardless of...
Mr. Bernhardt, I find your comment somewhat strange, ALL jokes.images are offensive to SOME groups of people. That is the whole nature of the beast. If a joke/image doesn't offend someone somewhere its pointless posting/telling.
We would no longer need a sense of humour or comedians of any...
Can your DC supply put out the required current for the stated voltage and coil resistance. Use Ohms law to calculate the current the coil will take. Current equals voltage divided by resistance. Now work out the current the coil will require from the supply.
I find this EV charge and the resell to the grid rather strange. I note that power suppliers are now wanting to disable solar fed into the grid since it reduces their income etc.
Also there is a problem that solar feed in that it has to be at a suffieient voltage to actually feed power in and...
Greetings,
From my reading of the above explanation, am I right in understanding that the particular atom and frequencies are so chosen because they closely match our previous definition of a second and are extremely stable or do we now have to completely "recalibrate" our second to match the...
"Fear AI". There may a few ways that we really should "fear" or at least be wary. The obvious one is where the "AI" is given access to physical controls of the real environment e.i. driverless vehicles of any kind or control of weapons (as per "The Corbin project (movie)). we also know what...
Thanks,sophiecentaur, for your reply. So my "deduction" was almost correct, in that it all revolves around wavelength and the difficulty of detection apparatus. The one issue I did not allow for was the energy factor. Maybe at some time technology will allow us to do this experiment for more EM...
Not a physicist. Background is in electronics over many years. Have recently been "binge" watching youtube lectures on the "dreaded" QUANTUM MECHANICS by various people(Susskind, Feynman et al) and trying to comprehend the whole thing.
While I can generally follow the lectures I must admit the...
Hi, You are trying to use an AC induction motor as a generator?Well, maybe my knowledge of electric motors may be outdated by now but I have NEVER heard of an AC single phase motor being able to be used as a "generator". Firstly the term "generator" as I know it refers to a machine designed to...
Have read all the dune series by F.Herbert. Wasnt impressed by the later books written after Herbert passed away. Have seen the first movies and the series with William Hurt and found them to very close to the story line in action and effects.
Have watched the trailer of the new movie and am...
Be aware of the danger of playing with mains voltages! Many. many years ago I attemped to make a transformer by winding a number of turns of household wire around a simple iron bar, wired a plug on the end and plugged it into a outlet(we use 240volts here ,by the way). Resulted in a nice flash...
