For example, if the charge held in the capacitor at some time is (Q), then the symbol (dot Q,text{ or }dQ/dt) means the rate of increase of (Q) with respect to time. If the capacitor is discharging, (dot Q) is negative. Expressed otherwise, the symbol to be used for the rate at which a capacitor is losing charge is (-dot Q).
