Why is V(R) < 0 for discharging in RC circuit?
The decrease in voltage during discharging in an RC circuit is a result of the flow of electrons from the capacitor to the resistor. As the capacitor releases its stored charge, the voltage across it decreases, causing a decrease in the overall voltage of the circuit.
The negative value of V(R) during discharging indicates that the current is flowing in the opposite direction of the voltage drop. This is because the capacitor is releasing its stored charge, causing the current to flow from the capacitor to the resistor in the opposite direction of the voltage drop.
The value of the resistor affects the rate at which the capacitor discharges and therefore, the voltage across the capacitor. A higher resistance will result in a slower discharge and a lower voltage, while a lower resistance will result in a faster discharge and a higher voltage.
No, V(R) cannot be positive during discharging in an RC circuit. This is because the capacitor is releasing its stored charge, causing the current to flow in the opposite direction of the voltage drop, resulting in a negative V(R) value.
The time constant, represented by the symbol τ, is a measure of how quickly the capacitor discharges in an RC circuit. A smaller time constant means the capacitor will discharge more quickly, resulting in a larger change in voltage during discharging. Conversely, a larger time constant means the capacitor will discharge more slowly, resulting in a smaller change in voltage during discharging.
