Every device we use has a unique circuit. It contains circuit components and proper biasing for its operation. Do you think that just these things are enough to deal with a circuit? No way. You have to take care of some other conditions. A circuit needs electric current for its operation. You are probably thinking … Read more
1k ohm carbon resistor is one of the popular resistors in Physics and Engineering laboratories. It has wide uses in different practical circuits. Carbon resistors are identified by the colors of bands on their surface. Therefore, one can calculate the resistance value of such resistors by reading the color codes. In this tutorial page, we … Read more
All bodies are neutral in nature. Charged bodies are created either artificially or by natural phenomena like lightning. There are three processes to charge a body artificially – Friction, Induction and Conduction. In this article, we will learn how to produce electric charge by induction process. Here, I am going to explain how can two … Read more
100 ohm carbon resistors are very much useful resistors in practical circuits. These are available with 3, 4 and 5 bands. We need to identify it by solving its color code. In this tutorial post, we’re going to explain how to read the color code of 100 ohm resistor to calculate its resistance without using … Read more
In Science and Engineering labs you may have seen carbon resistors. This type of resistor is usually painted with three, four, five or six bands of different colors. These bands are the codes from which one can find the value of the resistance of a resistor. Now, how to read resistor color code of carbon … Read more
Solar energy is a trending topic of science in recent times. The non-renewable sources of energy are about to extinct due to their limited storage on the Earth. Therefore, alternative sources of energy are needed to fulfill our daily needs of energy. There are some renewable sources of energy like Solar energy, Wind energy, Geothermal … Read more
People have a joy in seeing Rainbow in the fresh sky after a rainstorm. It looks very pleasing to our eyes. I use to find rainbow in the sky every time after the rainfall. But, what causes a Rainbow? Do you know that? I read in Physics book that a Rainbow has seven different colors. … Read more
Thermodynamics is a branch of Physics that deals with the thermal state of the gas system and other macroscopic systems. There are four laws of Thermodynamics – Zeroth Law, First Law, Second Law and Third Law of Thermodynamics. Sometimes, most of the students feel difficulties understanding these laws. In this post, I am going to … Read more
Thermodynamics is a branch of Physics that deals with the macroscopic variables like Temperature, Pressure, Volume, etc. of a system. These types of systems are known as Thermodynamic systems. There are four laws for these thermodynamic systems – Zeroth Law, First Law, Second Law and Third Law. We already have discussed the Zeroth law, second … Read more
To write a decimal number in short, we need to round off the numbers up to some significant figures. Suppose we have to present a long decimal number 65.3452343….. up to two or three significant figures after the decimal. This may look very easy, but it is not the case. There are some rules to … Read more
