Capacitor
A capacitor is classified under passive electronic components. It consist of two conducting surfaces separated by a layer of an insulating material called Dielectric. It allows the passage of AC but block DC.
Types of Capacitors:
A few of the commonly used capacitors are as follows:-
1. Mica Capacitors:- It consist of a series plate made from Mica material which are connected together and separated by the dielectric. Mica capacitor have very low power factors on AC and hence they are very suitable for use at Radio Frequencies.
2. Ceramic Capacitors:- It consist of disc of ceramic material whose opposite faces are coafted with metallic silver. The ceramic disc acts as the dielectric and silver coatings as plates. Ceramic capacitors also have very low power factor and is very suitable for shortwave work in radio.
3. Paper Capacitors:- It usually consist of metal coils made from aluminium or copper or tin with thin paper impregnated with oil or wax. They are suitable for use in audio frequency stages of radio receiver as bypass capacitors.
4. Electrolitic Capacitors:- They are neither wet type or dry type. The wet type consist of an aluminium annode with an electrolytic solution of ammonium borate as cathode. The dry type capacitors consist of positive and negative electrodes of aluminium foil separated by porous paper containing electrolytes. Due to their high capacitance, they are used in smoothing circuits in radio work. For successful operation, such capacitors must always be used with proper polarity.

Zener Diode
It is a reverse bias heavily doped P-N junction diode which is made from Silicon and Germanium semiconductor mainly. It is operated in the breakdown region where current is limited by both external resistance and power dissipation of the diode. Zener diode made from Silicon is prefer to Germanium because of its higher temperature and current capability.Uses/application of Zener Diode:-
1. Zener diode is used as voltage regulator.
2. Zener diode is used as peak differ.
3. Zener diode is used for calibrating volt meters.
4. Zener diode is used for metal protection against damaged from accidental applications of excessive voltage.
Light Emitting Diode(LED)
Light Emitting Diode (LED) is a forward biased PN junctions which emits visible lights when energized. It emits low light when reverse biased and if operated in the reverse direction, the LED will be quickly destroyed.
The construction of a light emitting diode is very different from that of a normal signal diode. The PN junction of an LED is surrounded by a transparent, hard plastic epoxy resign hemispherical shaped shell or body which protects the LED from both vibration and shock. Surprisingly, an LED junction does not actually emit that much light so the epoxy resin body is constructed in such a way that the photons of light emitted by the junction are reflected away from the surrounding substrate base to which the diode is attached and are focused upwards through the domed top of the LED, which itself acts like a lens concentrating the amount of light. This is why the emitted light appears to be brightest at the top of the LED.Application of LED:-
1. LED are used in burglar alarm system.
2. LED are used for the solid state video display which are rapidly replacing Cathode Ray Tube(CRT).
3. LED are used for numerical displays in pocket calculators.
4. LED are used for displaying alpha-numeric or supplying input powers to lasers for entering information into optical computer memories.
PN Junction Diode
A PN junction diode is formed by combining a P type semiconductor with N type semiconductor. It has the property of offering a low resistance to current flow in one direction and is the main components used in rectifying circuits. PN junction diodes are mainly manufactured using Germanium or Silicon semiconductor material.
Summary of Junction Diode
The PN junction region of a Junction Diode has the following important characteristics:
1). Semiconductors contain two types of mobile charge carriers, Holes and Electrons.
2). The holes are positively charged while the electrons negatively charged.
3). A semiconductor may be doped with donor impurities such as Antimony (N-type doping), so that it contains mobile charges which are primarily electrons.
4). A semiconductor may be doped with acceptor impurities such as Boron (P-type doping), so that it contains mobile charges which are mainly holes.5). The junction region itself has no charge carriers and is known as the depletion region.
6). The junction (depletion) region has a physical thickness that varies with the applied voltage.
7). When a diode is Zero Biased no external energy source is applied and a natural Potential Barrier is developed across a depletion layer which is approximately 0.5 to 0.7v for silicon diodes and approximately 0.3 of a volt for germanium diodes.
8). When a junction diode is Forward Biased the thickness of the depletion region reduces and the diode acts like a short circuit allowing full current to flow.
9). When a junction diode is Reverse Biased the thickness of the depletion region increases and the diode acts like an open circuit blocking any current flow, (only a very small leakage current).
