The simplest form of rectifier is the half wave rectifier shown.
•
Only the transformer, rectifier diode, and load (R L) 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.

Plan Training Session 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.
A typical LDR •
Circuit symbol of LDR
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

Plan Training Session 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.

Plan Training Session 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.

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
