Learning styles a. Visual - The visual learner takes mental
pictures of information given, so in order for
this kind of learner to retain information, oral
or written, presentations of new information
must contain diagrams and drawings,
preferably in color. The visual learner can't
concentrate with a lot of activity around him
and will focus better and learn faster in a
quiet study environment.
b. Kinesthetic - described as the students in the

their fingers on the desks. They are often
referred to as hyperactive students with
concentration issues.

remember speeches and lectures in detail
but has a hard time with written text. Having
to read long texts is pointless and will not be
retained by the auditory learner unless it is
read aloud.

e. Reflector - Learns most from activities where
they can watch, listen and then review what
has happened.
f. Theorist - Learns most when ideas are linked
to existing theories and concepts.

Power Supply
• All electronic circuits need a power source to work.
• For electronic circuits made up of transistors and/or ICs, this power source
must be a DC voltage of a specific value.
Power Supply Characteristics
• The input is the 120 volt 60 Hz AC power line. Alternately, the input may be
240 volt AC.
• The power supply converts the AC into DC and provides one or more DC
output voltages.
• Main circuits in most power supplies.

Power Supply
• The AC line is first passed through a low pass filter of the form shown in figure.
Transformer
A transformer is commonly used to step the input AC voltage level down or up.
Rectifier
 The rectifier converts the AC sine wave into a pulsating DC wave.
Regulator
• The regulator is a circuit that helps maintain a fixed or constant output
voltage.
DC-DC Converter
• Most modern power supplies also contain one or more DC-DC converters

How Rectifiers Work
• The simplest form of rectifier is the half wave rectifier shown.
• Only the transformer, rectifier diode, and load (RL) are shown without the
filter and other components.
Bridge Rectifier
• Another widely used rectifier is the bridge rectifier. It uses four diodes.
• This is called a full wave rectifier as it produces an output pulse for each half
cycle of the input sine wave.

How the Filter Works
• A large capacitor is connected across the load resistor. This capacitor filters
the pulses into a more constant DC.

Ripple
• The capacitor does a good job of smoothing the pulses from the rectifier
into a more constant DC.
The Regulator
• Most regulators are ICs .
• These are feedback control circuits that actually monitor the output voltage
to detect variations.

INTRODUCTION
• A light dependant resistor (LDR) or a photo resistor or photocell is a light
controlled variable resistor. Its resistance changes with the light intensity that
falls on it.
• They are made up of semiconductor materials having high resistance.
WORKING OF LDR
A LDR works on the principle of photoconductivity.
Photo conductivity is an optical phenomenon in which the materials
conductivity reduces when light is absorbed by the material.
CHARACTERISTICS OF LDR
LDRs are light dependent devices whose resistance decreases when light falls
on them and increases in the dark.
When a light dependent resistor is kept in dark, its resistance is very high. This
resistance is called as dark resistance.
CONSTRUCTION OF LDR
A typical LDR Circuit symbol of LDR

Electronic Products

March 26,2015
Bosconian Trainers
Revision # 02
Modern light dependent resistors are made of lead sulphide, lead selenide, indium
antimonide and most commonly cadmium sulphide (CdS) and cadmium selenide.
ADVANTAGES:
LDRs are cheap and are readily available in many sizes and shapes.
DISADVANTAGES:
Highly inaccurate with a response time of about tens or hundreds of milliseconds.
Light sensor: The LED lights up when the intensity of the light reaching the LDR
resistor is sufficient.
Example is Automatic Emergency Light: It senses darkness/night and turns
ON automatically. Similarly it senses day light and turns OFF automatically. Series
of LEDs are connected.

2. Audio Compressor: Audio compressors are devices which reduce the gain of the
audio amplifier when the amplitude of the signal is above a set value. This is done to
amplify soft sounds while preventing the loud sounds from clipping. Some compressors
use an LDR and a small lamp (LED) connected to the signal source to create changes
in signal gain.
3. Fire Alarm: The alarm works by sensing the smoke produced during fire. When there
is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance
will be low and so the voltage across it (below 0.7 V). The transistor will be OFF and
nothing happens. When there is sufficient smoke to mask the light from falling on LDR,
the LDR resistance increases and so do the voltage across it. The transistor will switch
ON which is connected to a tone player to play music.
4. Automatic Street Light: It automatically switches ON when the night falls and turns
OFF when the sun rises.

CIRCUIT OPERATION
 is a simple water level alarm circuit that will produce
an audible alarm when the water level reaches a preset level.
 The circuit can be powered of a (3 to 12V) battery and is very handy to use.
 The circuit is based on an astable multivibrator wired around IC1 (NE 555).
 The operating frequency of the astable multivibrator here will depend on
capacitor C1, resistances R1, R2 and the resistance across the probes A&B.
IC NE555
 The 555 can be used to provide time delays, as an oscillator, and as a flip-flop
element.

 PIN 2 “TRIGGER” Voltage below 1/3 Vcc to trigger the pulse
 PIN 3 “OUT” Pulsating output
 PIN 4 “RESET” interrupts the timing interval at Output.
 PIN 5 “CONTROL VOLTAGE” Provides access to the internal voltage divider;
default 2/3 Vcc.
 PIN 6 “THRESHOLD “The pulse ends when the voltage is greater than Control.
 PIN 7 “DISCHARGE ” Open collector output; to discharge the capacitor.
 PIN 8 “VCC” Positive supply voltage is usually between 3 and 15 V.
RESISTOR
 Resistor is a passive component used to control current in a circuit.
 Its resistance is given by the ratio of voltage applied across its
Terminals to the current passing through it.

 The piezo buzzer produces sound based on reverse of the piezoelectric effect.
 The generation of pressure variation or strain by the application of electric potential
across a piezoelectric material is the underlying principle.
CAPACITOR
 Capacitor is a widely used electronic component. It stores electric charge and
then discharges it into the circuit.
BATTERY[12V]
 It is a collection of one or more electrochemical cells in which stored chemical
energy is converted into electrical energy.
 The principles of operation haven’t changed much since the time of Volta.
Application & advantages
 Water level indicator is used in applications like storage tanks, boilers etc. to
indicate level of water inside.
 Easily indicate when water level is full in tank with beep
Sound.
 Low cost
