===Formula===
The '''discharge''' through a [[resistor]] follows an [[Exponential Decay|exponential decay]] described by the formulaformulae:
*<math>𝑄=𝑄_0𝑒^{−𝑡/𝑅𝐶}</math>
 *<math>𝑄V=𝑄_0𝑒V_0𝑒^\frac{−𝑡/𝑅𝐶}</math> *<math>I=I_0𝑒^{−𝑡/𝑅𝐶}</math> 
Where:
𝑄 𝑅 is the [[Electrical ChargeResistance|chargeresistance]] in the [[Electrical Circuit|circuit]],  𝐶 is the [[capacitance]] of the [[capacitor]], 𝑡 is [[time]] stored,
𝑄<sub>0</sub> is the initial [[Electrical Charge|charge]] storedat time t,  V is the [[Potential Difference|potential difference]] across the [[capacitor]] at time t,
𝑅 I is the [[Electrical ResistanceCurrent|resistancecurrent]] in being discharged by the [[Electrical Circuit|circuitcapacitor]]at time t,
𝐶 𝑄<sub>0</sub> is the initial [[capacitance]] of the [[capacitorElectrical Charge|charge]]stored,
andV<sub>0</sub> is the initial [[Potential Difference|potential difference]] across the [[capacitor]],
𝑡 I<sub>0</sub> is the initial [[timeElectrical Current|current]] through the [[Electrical Circuit|circuit]]
A [[capacitor]]'s rate of '''discharge''' in a [[Electrical Circuit|circuit]] is characterised by the [[Capacitor Time Constant|time constant]] 𝜏 which is given by the formula:
