Question Regarding the Distributed Capacitance of a Winding

AI Thread Summary
A winding with a regular capacitor connected to both terminals charges when a moving magnetic field induces voltage, creating a current that produces a magnetic field. In contrast, an open-circuit winding raises the question of whether induced voltage can charge the distributed capacitance without shorting the leads. It is suggested that distributed capacitance behaves like a discrete capacitor, requiring work to store energy, defined by voltage times current. The discussion emphasizes the need to consider how energy storage occurs in both scenarios. Understanding these principles is crucial for analyzing the behavior of windings in electromagnetic applications.

First, take the case of a winding with a regular capacitor connected to both terminals of the winding. When a moving magnetic field induces a voltage therein, the cap becomes charged and a current flows in the conductor while cap is charging, producing a magnetic field.
Next, take the case of a winding with the ends not connected, an open circuit. When a moving magnetic field induces a voltage in the open winding, will this induced voltage result in the charging of the distributed capacitance within the winding, or must the winding leads be shorted (closed circuit) in order to charge the distributed capacitance?

Thanks for the inspiration Bystander. Even though distributed capacitance is spread out over the entire winding it still must be regarded the same as a discrete cap in that to store energy into the cap work must still be done which means voltage times current.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
