===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<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,
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:
