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
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
There are three basic passive circuit components – Resistor, Capacitor and Inductor. One can find the voltage drop across a resistor simply by using Ohm’s law of current electricity. In another article, we have discussed different ways to find the voltage drop across a capacitor. Here I’m going to explain the formula and polarity of … Read more
In current electricity, we became to know that the flow of electric charges is electricity. Again, from Thermodynamics, we know that heat is an energy that can flow from one part to another part of a substance. You may have noticed that a wiring of copper (Cu) wire is used in our home or office … Read more
Power factor is an important parameter of an electrical circuit. To deal with a circuit, we need to know how much power is to be supplied to its components so that the circuit works. Because the dissipation of power in a circuit may not be the same as that of real power supplied by the … Read more
We already have discussed the Power factor of an electrical circuit and how to calculate the power factor, etc. You might have heard the term unity power factor while dealing with the power in electric AC circuits. In this article, we are going to discuss the concept and formula of Unity Power factor of an … Read more
In another article, we have discussed the power factor, its definition, its formula and other related facts on power factor. Now, we need to find the power factor in a circuit to know how much power is delivering to its output and how much power is losing in circuit components. In this article, we are … Read more
A Capacitor is an important component in an electrical circuit. We have discussed different types of capacitors in other articles. Like other components (resistors, inductors), a capacitor also offers opposition to the current flow (Direct current only) through it. That means it generates impedance. Ohm’s law tells us that an impedance causes a voltage drop. … Read more
Electrical components like resistors, capacitors, inductors and their combination offer an electrical impedance to the current flow. Ohm’s law gives an expression for the impedance (resistance) of a resistor in terms of current and voltage. But how to find the impedance of an inductor? In this article, I will explore the formula for the impedance … Read more
