WebOct 18, 2024 · As the capacitor discharges, q falls; thus its rate of change d q / d t is negative. However the current i flowing out is a positive current. In the equation i = d q / d t, we therefore also require the d q / d t side to be positive. But it is negative, so we add an extra minus sign to yield a minus times a minus, written as i = − d q / d t. WebFeb 27, 2015 · If a capacitor is discharging, current exits the more positive terminal rather than entering. That's really all there is to it. When current enters the more positive terminal, power is delivered to the capacitor and, thus, the stored energy increases. dragontooth crater

"WebFeb 20, 2024 · Discharging a capacitor through a resistor proceeds in a similar fashion, as Figure illustrates. Initially, the current is I 9 − V 0 R, driven by the initial voltage V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V. " - Discharging capacitor physics
