... At the end of the 19th century it was known that when a very high voltage was applied between the cathode (negative electrode) and the anode (positive electrode), the end of the gas filled tube would glow. A hole in one or more screens restricts the glow to a tiny spot. It seemed as if something bei ...

The mistery of magnetic voltage generation and Kirchhoff`s voltage law
... device. From Faraday’s law we know that Kirchhoff’s voltage law doesn’t hold any more as soon as a changing magnetic flux flows through our circuit. So the generators magnetic part certainly must have an impact on our circuit, but why can we still calculate the circuit using KVL? Why do the voltages ...
