You might have seen those thick electric cables that are used to transmit electric current to our homes from the power station. In this article, we will learn more about these electrical cables and their different types. What is Electrical…
What Is a Switch? A switch is an electrical component that is used to turn on and turn off any equipment like a television, washing machine, lights, fans, etc. When the switch is off, the circuit is open, and there…
Q1 What is a diode? A diode is an electrical device that allows the current to flow only in one direction. In a circuit figure, a diode is denoted by a triangle with a straight line across one vertex. Q2…
Introduction: LED (light-emitting diode) is a semiconductor light source that emits light when current flows through it. Their various types of LED are made of semiconductors and are classified into different categories. It is used due to its effectiveness in…
Q1 What is force? Force is pushing or pulling any object resulting from the object’s interaction with another object. Without force, nothing can be moved, stopped or changed. It is a quantitative interaction between two physical bodies, between an object…

Q1 What is a lever? A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. Q2 Name…
Levers are the most basic machines which are used to do some work with minimal effort. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. We are aware that there are…
Q1 What is an electric motor? It is an electrical device that transforms electrical energy into usable mechanical energy. Almost every electric motor operates by the interplay between the motor’s electric current and magnetic field in the form of torque…
