Why is V(R) < 0 for discharging in RC circuit?

AI Thread Summary
In an RC circuit, the voltage across the resistor, V(R), is negative during discharging because the polarity of the voltage changes as the capacitor releases its stored energy. When the capacitor discharges, the end of the resistor that was previously positive becomes less than the voltage of the capacitor, resulting in a negative voltage across the resistor. This behavior is a fundamental aspect of how capacitors and resistors interact in a circuit. The discussion emphasizes the importance of understanding voltage polarity in both charging and discharging phases. Overall, the relationship between voltage and current in RC circuits is crucial for analyzing their behavior.

You may get better responces if you provide more information. What is V(R)?
 
Lacking clarification I will plunge in anyway... Guessing that V(R) is the voltage across a resistor in an Resistor-Capacitor circuit, and further guessing that the circuit is being both charged and discharged through the same resistor... If one says the voltage is positive across the resistor when charging, it must be negative when discharging because the end of the resistor that _was_ positive must be switched to something that has a lower voltage than the charge on the capacitor in order to discharge it.

If there was an easy way to draw circuit diagrams I would do it and then what I'm trying to say would be fairly obvious, but I'm to lazy to figure it out...
