What are the Differences between Pillar & Column? Most people confuse when asked the difference between pillar & column. They often times interchange the meaning of these two terms. These terms share some similarities but they are quite different from each other. In this article, we will explain the differences between pillar & columns using a table chart. Before going into the list of differences, we are going to discuss what pillar & column is. Pillar Pillar is vertical structure designed to bear the  weight of building’s roof  & it can also be used as a  decorative  element in a structure. It can even stand on its own. Column Column is a structural member that transmits the  load of structure to the footing and the soil . In other words, column is a  compressive member  that is constructed from concrete, reinforcement concrete, bricks and blocks etc. Read more about Differences between Pillar & Column read more

What Is A Thyristor (SCR)? How Do They Work, Their Types & Applications A thyristor is a solid-state semiconductor switching device. It is a  bistable  switch that operates in two stable states; non-conducting and conducting state. They are said to be an ideal switch but practically they have some limitations based on their characteristics. They are mostly used in high power circuits.   Symbol Structure States Of Thyristor Working Of Thyristor Forward Blocking Forward Breakdown Gate Switching Reverse Blocking Turn On Methods 1) High Voltage 2) Gate Current 3) Thermal 4) Light 5) dv/dt Thyristor Failure & Its Protection 1  di/dt Protection 2  dv/dt Protection Types Of Thyristor 1) Phase-Controlled Thyristor (SCR) 2) Bidirectional Phase-Controlled Thyristor (BCT) 3) Fast Switching Thyristor (SCR) 4) Light-Activated Silicon-Controlled Rectifier (LASCR) 5) Bidirectional Triode Thyristor (TRIAC) 6) Reverse-Conducting Thyristor (RCT) 7) Gate Turn

What Are The Differences Between Footing & Foundation Footing and foundation both are some basic terminologies used in civil engineering. But there are still some people who don’t understand the difference between them. If you are one of them then this is the topic for you Foundation: A foundation is a structure that connects the superstructure with the ground and transfers the load from the superstructure to the ground. There are two types of foundation i.e. shallow foundation and deep foundation Footing: The term footing is used in conjunction with shallow foundations commonly. A footing is a foundation unit constructed in brickwork, masonry or concrete under the base of a wall or a column for the purpose of distributing the load over a large area.
