Electron mobility - All About Circuits
2008年4月25日 · question: copper has 1 outer electron. copper has 8.5 x 10^22 atoms/cm^3 and conductivity of 5.8 x 10^5 S/cm. Resistance is 1.7x10^-6 ohms. I found that temp is at 25 degrees C. I have to find the mobility (mu) of the conduction electrons.

2011年12月22日 · Again, slightly off. With a conductor a charge (excess electrons or minimum electrons) still distribute themselves evenly through out the material because of the electron mobility. With an insulator the electrons can not redistribute themselves, and this is a static (as in static electricity) charge on the surface of the material.
Is there anywhere to buy tunnel diodes? - All About Circuits
2019年9月25日 · Playing around with Falstad's simulator online, I stuck the two tunneling didoes into the circuit like that. I found out that they would do some pretty weird distortions to the signal inputted, causing a bunch of what I can describe as small square waves; which isn't a surprise seeing the characteristic curve—but knowing practically nothing about it, I was really …

2020年7月31日 · If you are using a Curtis controller in your mobility scooter you can download the manual for the particular Curtis controller model you have? Mine is a Curtis 1228. It will show you circuits for a Wig Wag throttle an Inverted Wig Wag throttle and a Twist throttle. Yours is an Inverted Wig Wag throttle.
Does current exist when there is no voltage? | All About Circuits
2011年7月2日 · Electrons don't carry energy, only charge. Photons are the energy carriers. Mass is not needed for energy transfer but the properties of mass affects the wave impedance of space when energy is transferred and alters the relationship of energy in the electric or magnetic fields.
Why do you need 2 probes in a voltmeter? | All About Circuits
2019年10月2日 · Because the air is such a good insulator (it inhibits the movement of charge), as the multi meter probe drains charge to the ground probe, no more charge can flow through the air to the probe, so essentially your probe is giving you a short to ground due to the lack of charge mobility in the air. Again some meters are better than others.
Does Transmition line radiate - All About Circuits
2017年3月6日 · An electron is an electron but how they are physically separated is what matters with the fields that are generated from that acceleration. First consider that no power leaves the physical antenna. It might seem strange at first to say that but the little power that's dissipated as heat in the physical antenna comes from the space around it.
Transistor is just not working - All About Circuits
2021年3月13日 · I have 5Volts on the emitter from an arduino. The base goes to a resistor (1k) and then to ground. The collector goes to a resistor (330) and then through a LED to ground. As far as I understood the ground connected to the base should get the electron flow going, so that the collector can light up the led (not conventional current). Is this wrong?
