and then returns from the capacitor to the source (negative). Therefore the capaci-
tor does not dissipate energy but it can store it and then restore it.
4.7 INDUCTORS
4.7.1 Inductance
The term solenoid refers to a coil, that is, a series
of loops wound into a tightly packed helix. A sole-
noid adopted in a circuit is called an inductor,
which is a passive device capable of generating
a magnetic eld of signicant value when current
ows throughit.
Just like resistors and capacitors, inductors
are another example of two-terminal devices. An
inductor is essentially a solenoid of conducting
material, typically a copper wi ...
