Newton’s laws of motion tell that translational motion is caused by a force. That means if we apply sufficient force on a body, it will move. But how to rotate an object? Can a force produce the rotational motion of a body? The answer will be yes, but not any type of force. For the … Read more
A system needs energy to do work. There are various forms of energy that are used for different purposes. Light energy is one of those. Lives on the Earth are highly dependent on the energy of light in many aspects. Sun is the only natural source of light in Earth. We are using sunlight directly … Read more
If we bring two electric charges close to each other, they exert a force on each other. This force is known as the electrostatic or electric force. It is a natural property of electric charges. Every electric charge or charged body exerts an electric force on another charged body near it. In this article, I’m … Read more
A p-n junction diode works properly in forward bias condition. Because a higher amount of current flows for this biasing condition. On the other hand, a very small amount of current flows through the diode when it is connected to a reverse bias. Again, a higher amount of reverse bias voltage can create a breakdown … Read more
Electrostatics Article – 7 Let a source charge Q produces an electric field E and a positive test charge q is placed at a distance r from the source charge. Coulomb’s law gives the expression for the electrostatic force on the positive charge q due to the source charge Q. Now, if we want to … Read more
Energy is a basic physical property of a system. Physics defines energy as the ability to do work. That means a system or a body can do work only if it has some energy. A system can store energy in many forms like Mechanical energy, Chemical Energy, Electrical energy, etc. Again, energy can be transformed … Read more
When an electric current flows through a resistor, a voltage drops across it. There is a simple way of measuring the voltage across a resistor by using a voltmeter. But, if we need to calculate it from the circuit parameters, then how can we do that? In this article, I’m going to explain the formula … Read more
Every device we use contains a circuit in it. A circuit consists of some circuit elements that are used for different purposes. These elements in a circuit can be connected in different ways depending on the functions for which these circuits are used. Based on the types of connections of the elements, electric circuits are … Read more
100k Ohm carbon film resistor is a popular resistor in electrical circuits. It can be available with three, four, five or six bands. These bands have different colors which are known as the color code. To know the resistance value of the resistor, we should know how to read the color code. The resistor color … Read more
10k Ohm resistor is frequently used in electrical circuits. To design a practical circuit that contains 10000-ohm resistors, then the easiest option is to choose 10k ohm carbon film resistors. Because they have bulk availability in the market with the cheapest prices. But, the problem with carbon resistors is that most of the students don’t … Read more
