#6.1.3a
(i) charging and discharging capacitor through a resistor
(ii) techniques and procedures to investigate the charge and the discharge of a capacitor using both meters and data-loggers
PAG9
#6.1.3b
time constant of a capacitor–resistor circuit;
\(τ = CR \)
#6.1.3c
equations of the form \(x = x_0e^{-t/(CR)} \) and \(x = x_0\Big(1 - e^{-t/(CR)}\Big)\) for capacitor–resistor circuits
Learners will be expected to know how lnx–t graphs can be used to determine CR.
#6.1.3d
graphical methods and spreadsheet modelling of the equation \(\dfrac{ΔQ}{Δt} = -\dfrac{Q}{CR} \) for a discharging capacitor
#6.1.3e
exponential decay graph; constant-ratio property of such a graph.
