An Introduction to Insulating And Dielectric Materials Definition of Insulating and Dielectric Materials An electrical insulating material can be defined as the material that does not allow electric current to pass through it. For electrical applications a particular category of insulating materials is used to separate electrically the conducting parts of equipment from each other and from earthed and “no …

What is Fuzzy Logic System? Introduction to Fuzzy Logic Fuzzy Logic is a logic or control system of an n-valued logic system which uses the degrees of state “degrees of truth“of the inputs and produces outputs which depend on the states of the inputs and rate of change of these states (rather than the usual “true or false” (1 or …

Earthing and Types of Electrical Earthing | Electrical Grounding Installation (Step by Step) Earthing, Grounding, Methods Of Earthing, Types of Earthing And Is Specifications In Respect To Earthing Of Electrical Installations What is Grounding or Earthing? To connect the metallic (conductive) Parts of an Electric appliance or installations to the earth (ground) is called Earthing or Grounding. In other words, …

Basic Electrical Engineering Tools, Instrument, Devices & Equipments Electrical engineers are required to work in hazardous environments near energized equipment. There are certain tools they require to carry out their job effectively and safely without causing any harm to themselves and those around them. Here’s a sneak peek into some electrical engineering tools and their uses. Related Post: How to …

Unilateral circuits In unilateral circuits, the property of circuit changes with the change of direction of supply voltage or current. In other words, unilateral circuit allows the current to flow only in one direction. Diode rectifier is the best example of unilateral circuit because it does not perform the rectification in both direction of supply. Bi-lateral circuits In bilateral circuits, …

The Main Difference between Linear and Nonlinear Circuit Linear Circuit In simple words, a linear circuit is an electric circuit in which circuit parameters (Resistance, inductance, capacitance, waveform, frequency etc) are constant. In other words, a circuit whose parameters are not changed with respect to Current and Voltage is called Linear Circuit. Fundamentally, the word “linear” literally means “along with …

Ohm’s Law The relationship between Current through and Voltage across a conductor was first discovered by a German scientist George Simon Ohm. This relationship is called Ohm’s Law and be stated as; The Current “I” flowing through a conductor is directly proportional to the potential difference i.e. Voltage “V” across its ends provided the physical conditions (i.e. temperature, strain, etc) do …
