A2 Physics Capacitance

what is capacitance

electrical devices used to store energy

formula for capacitance

C = Q/V

derive formula for capacitance in series

derive formula for capacitance in parallel

how can you determine the electric potential energy stored in a capacitor by using a potential-charge graph

use the area under the potential-charge graph

formula for for electric potential energy (work)

draw the graphs of the variation of p.d., charge and current of a capacitor discharging through a resistor

why is there exponential decay in the graphs

as capacitor discharges, curret, p.d. and charge decrease. the rate at which I/V/Q decreases is proportional to I/V/Q it has left

formula for time constant for a capacitor discharging through a resistor

equations involving discharge of a capacitor
