## what is Diode?

#Technical studies-study 2 Introduction PN junction Diodes are the basic semiconductor devices those allow current to flow only in one direction. This is a nonlinear device because the graph of its current and voltage is not a straight line. The Read More …

## What are Semiconductors ?

#Technical studies- study 1 Introduction We know that conductors are those materials who allow current to flow through them freely and insulators are those materials who does not allow current to flow but semiconductors are the material which property lies Read More …

## Ohm’s Law – Statement and problems

#Technical studies – Study 25 In 1827 German scientist George Simon Ohm discovered the relationship between voltage, current and resistance in dc circuits. This relationship is named as ohm’s law. Ohms law states that:- At a constant temperature, current flowing Read More …

## Definitions of electrical terms – Basics of electrical

#Technical Studies – Study 24 Introduction Electrical technology is the branch of engineering that deals with the flow of current in conductors. We all know that electricity is very essential for us and we use it for various purposes in Read More …

## What are Pneumatic Motors? Types of pneumatic motors

Technical Studies – Study 23 Introduction Pneumatic motor is a rotary actuator that converts pneumatic energy into mechanical rotary motion. Pneumatic motors are widely used due to their advantages. Advantages of pneumatic motors are – Torque and speed of pneumatic Read More …

## Types of Pneumatic Cylinder

Technical Studies – Study 22 Pneumatic cylinders are the linear actuators that convert the pneumatic energy into mechanical energy. Pneumatic cylinders are of two types – Single acting cylinder Double acting cylinder Single acting cylinder (SAC): A Single acting cylinder Read More …

## What is Subtractor in Digital Electronics

#Technical studies – Study 21 Introduction In digital system subtractor is a combinational logic circuit that perform an arithmetic operation called subtraction. This operation is same as the 1’s complement method in binary number system. The rules of binary subtraction Read More …

## Adder Circuits (Digital Electronics) – Half and Full adder logic diagrams

#Technical studies – Study 20 Introduction Adders in digital system are the combinational logic circuits that perform an arithmetic  operation called addition. The binary addition rules are – 0+0=0, 0+1=1, 1+0=1, 1+1=10 In the four rules stated above, the first Read More …

## Clamper circuit using diode and its applications

#Technical studies – Study 19 Introduction A clamper is a circuit that adds a dc voltage to the input ac signal. It can shift the ac signal either up or down up to a dc level. Clamper circuits are widely Read More …

## Clipper circuit using Diode and its applications

#Technical studies – Study 18 Introduction A clipper is a circuit that removes positive half cycle, negative half cycle or both half cycles of the input waveform. This type of circuit is useful for wave shaping, voltage limiting applications. Positive Read More …
