Q=It where t is time
Capacitance is measured in Farads
C = Q/v
Capacitors are used in flash photography, defibrillators and back up power supplies
The shorter the time taken for the capacitor to discharge, the higher I
E = ½ Qv = ½CV2 = ½Q2/C
The factors affecting time of charge/discharge are capacitance and resistance
The charge decreases exponentially (instant charge, exponential discharge)
