1. Different types Electronic Components
and their working
Electronic gadgets have become a key element in our lives. They are designed to make our lives
comfortable and convenient. From aviation to the health industry, electronic gadgets are used in a wide
range of applications in today’s modern world. Even some gadgets use small tiny circuits to control
machines and process information. They are the lifeline of various electrical appliances. In this article,
we are talking about different electronic components and how it works?
1. Capacitors
This component is extensively used in building different types of electronic circuits. A capacitor is
considered a passive two-terminal electrical component used for storing energy in an electric field. In
other words, it will work as a small rechargeable battery for storing electricity.
How does it work?
When the voltage is applied on two plates or connect to a source, an electric field will develop across
the insulator. As a result on plate accumulate a positive charge while others will negatively be charged.
The capacitor will hold its charge even after it is disconnecting from the source. The moment you
connect it to load the stored energy will flow from the capacitor to the lead. Capacitance is used for
calculating the amount of energy stored in a capacitor. The higher capacitance means the more energy
can be stored in it. By moving the plates close to each other or increasing their size you can increase the
capacitance.
2. Resistor
A resistor is a passive two-terminal electrical device which can resist the flow of current. It is a simple
element used in an electronic circuit. This is one of the common components which work as resistance
in the inherent element of nearly all electronic circuit.
How does it work?
Resistors perform a key role in controlling voltage and current in the circuit. In other words, they
provide you control over the design of the circuit. When an electric current starts to flow through a
wire, the electrons will also start moving in the same direction. The current pass through a thin wire in a

2. resistor will become progressively harder for electrons to jiggle through it. It means, if the number of
electrons flows through the resistor goes down, the length and thinness of the wire also increase.
3. Diode
A diode is a two-terminal device that enables the current to flow in one direction only. This is a reason, it
is considered as an electronic equivalent of a check valve or one-way street. It is used for converting
alternating current into direct current. A diode is made with either semiconductor material or a vacuum
tube. Today, most diodes are made by using semiconductor material, particularly silicon.
How does it work?
A diode’s working mainly depends on the interaction of p-type and n-type semiconductors. An n-type
semiconductor contains a lot of free electrons and few numbers of holes. Or we can say that
concentration of free electrons is high and holes are low in the n-type semiconductor. The free electrons
of n-type semiconductors refer to as majority charge carriers and holes are known as minority charge
carriers.
A p-type semiconductor contains a high concentration of holes and a low concentration of free
electrons. Holes in p-type semiconductors comprise charge carriers and free electrons in p-type
semiconductors are minor charge carriers.
• Inductor
This is also called a reactor and passive component of circuit contain two terminals. The device is stored
energy in magnetic field and get back to circuit when needed. It was identified when two inductors are
placed side by side without getting touched. The magnetic field is created by first inductors which affect
the second inductors. This has led to the first transformers invention.
How Does It Work?
When current passes from the wire it create magnetic field. But, the unique shape of inductor create
stronger magnetic field. The powerful magnetic field will turn and resist the alternate current but let
the direct current flow from it. This magnetic field is also capable of storing energy.
Take a circuit contain battery, switch and bulb. The bulb will glow brightly for a moment and turn off.
Just add an inductor to this circuit. When you turn the switch on, the bulb will changes from bright to
dim. On the other hand, when switch is turn off, it become bright in fraction of second before turning
off.
These are a few types of electronic components and a brief idea of how they work. If you are looking for
an outstanding range of top quality electronic components then you should buy from trusted companies
like Express technologies. It is one of the reckoned Electronic Components Store, which only deal in
premium quality electronic components with outstanding shipping services. Whether you need diodes,
