I know that for products produced in the EU and United States, I needn't worry about lead on components. That being said, I many times purchase products from Chinese sellers due to the low bulk price. I recently read that an electrical engineer with the tendency to chew wires while stripping...
I apologise for the late response -- I appreciate the assistance and have now realized that I neglected several sections of an excellent textbook on electronic theory given to me.
From the research I have done, I believe I have fully grasped the concept of impedance -- my initial problem being is that I suspected it had to do a lot with lenz' law, but no sources clearly stated one way or another. What I need is verification that I am correct or to be corrected...
My base understanding of the solar cell is as follows: Light hits metal in solar cell and emits electron via photoelectric effect. There is n-type silicon which has an overall negative charge due to excess electrons. There is also p-type silicon which has an overall positive charge due to a...
First of all, from what I've read the descriptions of an observation or measurement in Quantum Mechanics have been quite vague. Since the word measurement is used alternatively I am going to assume that this includes all types of measurements, which brings me to a question. If the box...
We all know Ohm's law and power conservation, but in a basic transformer, they seem to be contradictory. For example, say we have a 50v source running through a 10Ω wire, then the amperage to the transformer should be 5 A and would come out to 250 watts. Then say the transformer steps the...
Due to the fact that I don't have any plans on damaging my chargers (something I am not planning to risk at the moment) I have not been able to confirm whether the transformers in chargers act as a load when nothing is charging. From what I have read, based on the design of many chargers, even...
Why exactly is it that a spark is created when capacitors are shorted? Even with a few volts capacitors will spark when shorted, with my limited somewhat basic knowledge this has puzzled me. Any help is greatly appreciated.
Hello, I am currently attempting to improve my math skills, understanding of modern physics, and extend my knowledge of two "coding" languages. One thing that has been at the back of my mind, and has been quite bothersome lately is that I am taking in too much at once. While I haven't been...
Thanks, I was thinking to rig up a sort of spring and just use Hooke's Law. I'm guessing I could probably use a ruler and sheet of paper to mark the spring's peak and compression.
I am currently working on an experiment with piezoelectricity and was wondering how I would measure the force applied to the crystal. I have been tapping the crystal with a screw driver and was wondering how I would calculate the force of these taps as I cannot find the amount of displacement in...
I am currently planning a Piezoelectric "experiment" and need to finish it in 22 days. I have no problem obtaining a clamp and synthesising rochelle salt. However, I need two things. One is something which I could use to measure the force applied to the crystal when tapped and two a cheap...
Why does air on Earth float? Obviously, lighter gases such as Helium and even hot air will float due to having a lowed density than the air around it. Why is it though that the base higher density gases that we breath float rather than sink to the ground? My belief is that gravity is simply too...
I am well aware that objects of varying masses, shapes, and surface areas will fall at different speeds and accelerations in an environment with a gas in the way such as air due to air resistance. Why is it though, that gravity causes all objects to fall with the same acceleration in a vacuum...
