V<sub>0</sub> is the initial [[Potential Difference|potential difference]] across the [[capacitor]],
I<sub>0</sub> is the initial [[Electrical 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:
