Capacity of a capacitor
The relation between the amount of charge Q on the positive electrode, and the voltage drop
across the two electrodes of a capacitor is the electrical capacity
of the capacitor:
|
The capacity is always a positive quantity and is measured in Farads.
The higher the capacity, the higher the charge that can be stocked on the positive electrode for a given polarisation voltage
.
Remarque : Remark
The higher the capacity, the lower the voltage drop for a given quantity of charges.
