When resistors are connected to these devices in a circuit, the time constant for the decay of current is directly proportional to both the resistance and their strength. The impedance of these devices is inversely proportional to the frequency, and energy stored in them is proportional to voltage squared. The strength of these devices can be increased by a dielectric, and their namesake quantity adds when they are placed in parallel in a circuit. Their strength is given by the amount of charge they store per volt, which is measured in farads.
