Speaker says 8Ω, but should be 16, why?
ByAmbi04
As you can see in the pictures, the diaphragms are printed with "8Ω." My guess is that they're connected in series, which should result in a total resistance of 16Ω (R total = R 1 + R 2 ). However, the speaker itself also says "8 Ohm." Why is that? Where's my mistake?
How far can satellites fly?
So solar and wind power probably won’t get you very far? But the free energy magnetic field is interesting!!! He would be self-sufficient in energy? It also does not depend on wind and sun. But now you can send spaceships with it. Unmanned. Small Stirling with magnifying glass sun, and magnetic field drive high. Plate…

What do you use? Sprays are probably best, but other products are also welcome.
Electrical engineering school assignment?
Can anyone help me with this task? What happens if you connect three identical lamps (3.8V/0.07A) to a 4.5V flat battery? In a parallel connection 1.each lamp shines equally brightly 2.The first lamp shines slightly brighter 3. all lights flash 4.no lamp lights up
Good weather for short clothes in Madrid?
Hello! I'm going to Madrid with my class next week and wanted to ask if we could wear shorts there. The weather forecast says it's sunny, but it's only 20°C, so I wanted to ask here to be sure.
I would rather leave because the additional EM radiation does not bring any positive effects.
Depends. The lightning “seeking” tends to be the “shortest” means the most resistant way. A copper mat of course has a very low resistance, but one must always look at the overall path of lightning.
Do you like to sleep outdoors with thunderstorms or why should the lightning strike in your bed?
An earthing is not such a mat. It could be helpful to create a similar potential along your body, but is not a Faraday cage. And she lies under you – if she is over you, where the lightning comes from, the effect would be somewhat greater.
If the lightning hits you in the bed, the mat won’t help you or not much.
When the mat is connected to the door of the house, a blice strike in the vicinity of the house can come very well over the ground to the mat, as with all the Electeo devices that are inserted. It’s called ‘indirect flash’. That would be fatal.
So make sure the mat is not grounded. But then it doesn’t make any sense against EM radiation.
Think a look into the physics books could not hurt here!
Hope could still help you with my assessment. May everyone see how he wants. Greetings
If there is only one placebo, there is no need to form a Faraday caefig 🙂
Your speeches are all right. Except for ‘directly under the sender’. There’s the least the radiation, the most ‘safe’ place.
Neither does a copper mat influence the lightning behavior, nor does it shield anything. Only if the mat was completely surrounded by you, so you would be really shielded.
The mat could focus more on “big rays”. Try Wi-Fi, phone on the copper mat.
It’s probably nix.
If it’s not grounded, nothing happens
Sure? The grounding of electrical devices and metallic objects ensures that potential differences are minimized. No potential = no current = no danger.
Nonetheless, there is no risk of the copper mat, since there should be sufficient distance/insulation to other conductive objects, so that no spark can skip
Electricity always seeks the shortest way. And in the rarest cases, he goes over a bed.
Exactly.
As I said, I cannot say much about the technical/physical subtleties of foundations, depth springs, ringers, lightning protection system on the roof and overvoltage protection type A, B, C. I can ask my experts again on occasion.
I only know grounding/potential compensation is important for the protection of humans and materials.
That’s what you’ve got in a flash anyway.
However, this statement also depends on lightning protection itself. If the lightning protection is placed around the house as a ring and is tied into the potential compensation.
The latter prevents exactly the case you describe.
That’s true. However, it is so: a flash impact increases the electrical potential in the environment for a short time.
All that is well grounded is raised to the same potential.
All that is not well grounded remains at the original potential.
There are thus voltage differences. If the voltage is sufficiently high and the resistance is sufficiently low, the arc/short circuit occurs. This can damage fine electronics or trigger a fire in unfavorable cases.
Now I’m not an expert on lightning protection and earthing. But I know an expert who explained it to me about a long time ago.
So it is not about the entire stream of lightning being able to find a way over the bed, but that a fraction of the lightning current could find a way to cause damage somewhere.
You should connect the mat to the lightning arrester.
Why should a lightning strike – don’t you have a lightning arrester?
Indirect flash can be an oroblem. Then the electricity comes to the house via the grounding line.
