AI Thread Summary
In RC and RL circuits, capacitors and inductors do not function as ideal current and voltage sources, respectively. A charged capacitor discharges nonlinearly into a resistive load rather than supplying constant current, which is characteristic of a true current source. Similarly, a fully energized inductor does not provide a constant voltage; instead, it releases energy nonlinearly when the current is interrupted. Both components absorb energy rather than consistently supplying it, which differentiates them from ideal sources. Understanding these behaviors is crucial for analyzing circuit dynamics effectively.

Does the capacitor acts as a current source and the inductor acts as the voltage source in the RC and RL circuits respectively? If so why does the capacitor not act as a voltage source and inductor not act as a current source?

Thankyou

No. Both the capacitor and inductor actually absorb energy. A fully charged capacitor (energized) will discharge nonlinearly into a resistive load. A current source in theory should supply constant current into any load.

A fully energized inductor (where current is flowing through it) will not supply a constant voltage into a load, as required by a voltage source. When the current through the coil is cut off, the magnetic field will collapse and release energy, thus inducing a voltage nonlinearly.
 
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...
