The IR measurement test is a...
by Tarun Agarwal 4 years ago What is Resistance : Definition, Formula and Laws The flow of electrons in a material produces electricity. These electrons do not travel in a straight path but have to undergo collisions. Based on the amount of electricity the material allows to pass, all materials are categorized as...
by Tarun Agarwal 4 years ago What is Electrical Resistance – An Overview The materials are categorized into two different types namely conductors and insulators. A conductor allows the flow of current whereas an insulator doesn’t. So the conductor materials should require the resistor components in their structure....
by Tarun Agarwal 4 years ago Difference between Resistance and Resistivity The resistance and resistivity concept is one of the most fundamental as well as an essential part of the concept of current & electricity. The major difference between resistance and resistivity of the material is that the resistance...
by Tarun Agarwal 4 years ago What is Specific Resistance : Formula and Its Units The resistivity otherwise specific resistance is the resistance in ohms recommend through a material that has a unit volume to the current supply. Resistivity is the mutual of conductivity. A material that has resistivity high, then the...
by Tarun Agarwal 4 years ago Temperature Coefficient of Resistance : Formula and Measuring Method In electrical or electronic engineering, when the flow of current supplies through a wire then it gets heat because of the wire’s resistance. In perfect condition, resistance must be ‘0’ however that doesn’t take place. When the...
by Tarun Agarwal 5 years ago Resistance Welding : Working Principle, Types and Applications In olden days, the process of metal welding can be done by heating the metals and pressed jointly which is known as forge welding method. But at present, the welding technology has been changed by the arrival of electricity. In the 19th...
by Tarun Agarwal 9 years ago How to find out the Resistance Value using Resistor Color Code Calculator? The discovery of electric current during the early 1600 year made to study other electrical properties of conducting substances or materials. The property of conducting materials to oppose the flow of electric current was discovered in...
by Tarun Agarwal 9 years ago Online Ohms Law Calculator to Find Voltage, Power, Current and Resistance The three essential electrical quantities like resistance, current and voltage. Of the three, current is the one that carries energy through a circuit. If you’ve been operating with circuits, you probably have an idea of how resistance,...
