This section will include brief explanation about the topics learnt,
sketches/drawings, tabulations, calculations, and graphs, if any.
A Zener diode operates just like a normal diode when it is forward-biased. However,
a small leakage current flows through the diode when connected in reverse biased
mode. As the reverse voltage increases to the predetermined breakdown voltage (Vz),
current starts flowing through the diode
A component tester is used to test if components are working correctly in circuit. This is very
nice if you do electronic repairs.
A component tester is used to test if components are working correctly in circuit. This is
very nice if you do electronic repairs. You can test components directly on a soldered PCB.
Generally, CRO provides built-in electronic component tester in it , which is used for
instant display of a test pattern to indicate whether or not components are faulty.
It can be used for quick checks of semiconductors (e.g. diodes and transistors),
resistors, capacitors, and inductors. Certain tests can also be made to integrated circuits. All
these components can be tested individually, or in circuit provided that it is non-powered.
Half wave rectifier, Full wave
rectifier:
A Half-Wave rectifier is an electronic circuit which converts only one-half of the AC cycle into
pulsating DC. It utilizes only half of AC cycle for the conversion process. On the other hand,
Full wave rectifier is an electronic circuit which converts entire cycle of AC into Pulsating DC.
Testing of common anode seven segment display using digital trainer kit:
How to use the 4511 7-segment decoder/display driver IC
Gain familiarity with the BCD code
How to use 7-segment LED assemblies to create decimal digit displays
How to identify and use both “active-low” and “active-high” logic inputs
The 555 Timer IC can be connected either in its Monostable mode thereby producing a
precision timer of a fixed time duration, or in its Bistable mode to produce a flip-flop type
switching action. But we can also connect the 555 timer IC in an Astable mode to produce a very
stable 555 Oscillator circuit for generating highly accurate free running waveforms whose
output frequency can be adjusted by means of an externally connected RC tank circuit consisting
of just two resistors and a capacitor.
Break failure indication using IC 555:
The 555 Timer operates in Astable mode to produce clock pulse and the BC557 PNP
Transistor monitors the Brake wire and decides which led should glow. 555 Timers in
Astable Mode: The Astable mode in a 555 timer is mainly used for Blinking LEDs or to do some
periodic Turn On and Turn off actions.
Push-Pull Amplifier is a power amplifier which is used to supply high power to the load. It
consists of two transistors in which one is NPN and another is PNP. One transistor pushes the
output on positive half cycle and other pulls on negative half cycle, this is why it is known as
Push-Pull Amplifier
SKILLS ACQUIRED
Dual power supply working and measuring voltage and current using multi-
meter
After the internship with proper guidance of professors I am now able to do all the connections
and maintain a proper software design on Eagle software.
