1)Passive components and 2).Active
components.
What are the examples of passive components?
How about active components?
Resistors, capacitors, Inductors
Diode, Transistors, SCR
2 – Presentation
Electronic components are specified by their parameters. A parameter is some property of the
component that has a numerical value, and describes one feature of the component's performance. The
values of a given component's parameters are found in the manufacturer's data sheet and are usually
called the "specs" (specifications).
Let us review first the basic components and how it works.
Resistors:
In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages,
bias active elements, and terminate transmission lines, among other uses.
High-power resistors that can dissipate many watts of electrical power as heat may be used as part of
motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have
resistances that only change slightly with temperature, time or operating voltage. Variable resistors can
be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for
heat, light, humidity, force, or chemical activity.
Capacitors:
A capacitor is a passive two-terminal electrical component that stores electrical energy in an electric
field. Capacitors come in several different varieties, the two most common being ceramic disk and
electrolytic. The amount of capacitance of a given capacitor is usually measured in microfarads,
abbreviated μF.
Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating
current to pass.
Diodes:
A diode is active device that lets current flow in only one direction. A diode has two terminals, called the
anode and the cathode. Current will flow through the diode only when positive voltage is applied to the
anode and negative voltage to the cathode. If these voltages are reversed, current will not flow.
Light-Emitting Diodes:
A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which
emits light when activated.
When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes
within the device, releasing energy in the form of photons. This effect is called electroluminescence, and
the color of the light (corresponding to the energy of the photon) is determined by the energy band gap
of the semiconductor.
Transistors:
A transistor is a three-terminal active device in which a voltage applied to one of the terminals (called
the base) can control current that flows across the other two terminals (called the collector and the
emitter). The transistor is one of the most important devices in electronics.
It is a semiconductor device used to amplify or switch electronic signals and electrical power. It is
composed of semiconductor material usually with at least three terminals for connection to an external
circuit.
Integrated Circuits:
An integrated circuit is a set of electronic circuits on one small flat piece (or “chip”) of semiconductor
material, normally silicon. The integration of large numbers of tiny transistors into a small chip resulted
in circuits that are orders of magnitude smaller, cheaper, and faster than those constructed of discrete
electronic components.
ICs have two main advantages over discrete circuits: cost and performance. Cost is low because the
chips, with all their components, are printed as a unit by photolithography rather than being
constructed one transistor at a time. Furthermore, packaged ICs use much less material than discrete
circuits. Performance is high because the IC’s components switch quickly and consume little power
(compared to their discrete counterparts) because of their small size and close proximity
