Lesson proper
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.

Lesson proper 2
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

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.

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.
