Calculate current and/or voltage in simple inductive, capacitive, and resistive circuits. Many circuits also contain capacitors and inductors, in addition to resistors and an AC voltage source. We have seen how capacitors and inductors respond to DC voltage when it is switched on and off.

Calculate the inductance of an inductor. Calculate the energy stored in an inductor. Calculate the emf generated in an inductor. Inductors. Induction is the process in which an emf is induced by changing magnetic flux. Many examples have been discussed so far, some more effective than others.
Inductor Voltage and Current Relationship. The instantaneous voltage drop across an inductor is directly proportional to the rate of change of the current passing through the inductor. The mathematical relationship is given by v = L (di/dt). Inductors do not have a stable “ resistance ” as conductors do.
Suppose we start building up a current from zero into an inductor. With no current in it, there is no magnetic field and therefore zero energy, but as the current rises, the magnetic field grows, and the energy stored grows with it. We actually have a way of determining the rate at which the energy stored is growing from what we know already ...
The self-induced emf in a circuit is directly proportional to the time rate of change of the current (dI/dt) multiplied by a constant (L). This constant is called the inductance (or more precisely, the self inductance) and is determined by the geometry of a circuit (or more commonly, by the geometry of the individual circuit elements). For ...

Derive an equation for the voltage and current through a circuit made of a resis-tor and inductor in series (an RL circuit), and for a circuit made of a capacitor and inductor in series (an LC circuit). Both circuits should give time dependent equations.
