Discharging a capacitor
19.3What the syllabus asks of you
- analyse graphs of the variation with time of potential difference, charge and current for a capacitor discharging through a resistor
- recall and use τ = RC for the time constant for a capacitor discharging through a resistor
- use equations of the form x = x0 e–(t / RC) where x could represent current, charge or potential difference for a capacitor discharging through a resistor
