Document Summary

V is the voltage between the two components this only comes from the voltage of the battery if the capacitor is fully charged. 1 t id + v(t0) dv (t) dt dt dq dt. The capacitance is the number which tells you how good a capacitor is at storing charge. The only way to change the capacitance of a capacitor is to alter its physical characteristics such as size or distance between plates. Thus, current is the slope of the voltage-time graph multiplied by the capacitance. Dielectric material, found between the plates of a capacitor, does not impede electric fields, but does block the flow of current. The time constant is the time it takes a capacitor to reach 63% of its maximum potential storage. The charge across a capacitor reaches some maximum value at infinite time. V c (t) = v ( ) + [v (0 ) v ( )]e t.
