The various applications of capacitors and inductors
In a DC circuit, when a capacitor is added in series with a resistor, the current initially becomes high but later falls to zero. In a DC circuit, when an inductor is added in series with a resistor, the value of the current is small and increases later over time. Capacitance is measured in units called farads.
