RLC Circuits (Alternating Current)

In a purely inductive circuit, we use the properties of an inductor to show characteristic relations for the circuit. Considering the flow of a time-dependent current (I) through the circuit shown below enables us to use the concept of induced emf due to the changing current in the inductor. So, according to Kirchoff''s voltage law for closed loops, we get (V={ V }_{ L }.)

20.5: RC Circuits

Discharging. Discharging a capacitor through a resistor proceeds in a similar fashion, as illustrates. Initially, the current is I 0 =V 0 /R, driven by the initial voltage V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V.

For a perfect capacitor, voltage drop always lags current by 90 o, and so a capacitor''s impedance phase angle is said to be -90 o. Impedances in AC behave analogously to resistances in DC circuits: they add in series, and they diminish in parallel. A revised version of Ohm''s Law, based on impedance rather than resistance, looks like this:
