Kirchhoff’s Current Law is one of the fundamental laws in Electrical and Electronics Engineering. Also known as KCL, the law explains the behavior of current in parallel circuits. Statement: The sum of electrical current entering a node is equal to sum of current leaving the node. Mathematically Σ Current In = Σ Current Out Let’s … Read more
Delta and Wye are two special configurations of electrical circuits. In this post, you’ll learn the formula for Delta to Wye conversion. We previously studied series, parallel and series-parallel circuits. Besides these three circuits, there are two special configurations: The Delta or Pi configuration The Wye or Tee configuration Delta and Wye circuits contain three … Read more
Synchronous motor belongs to AC class of motor which operates at a constant speed from no-load condition to full load condition. Due to its fixed speed characteristics, the synchronous motor is widely employed in industries. Besides of this induction motors are also used for the improvement of power factor in three-phase AC circuits. Given below … Read more

The Overhead system for power transmission started in early 1912. Although underground power systems are widely replacing low, and medium voltage transmission networks within cities, the use of overhead lines for high voltage networks outside cities can never be negated. Given below are 10 differences between overhead and underground transmission lines. Initial cost: The initial … Read more
A sensor is a device which converts physical parameters to some electrical signal. A sensor senses some physical property (such as temperature, speed, presence of object, motion, acceleration) and converts it to some electrical property signal. Given below are topmost sensors that are used in Electrical and Electronics Industry. Proximity sensor A proximity sensor is … Read more
The resistor is a two-terminal electrical component which implements electrical resistance in a circuit. On a broad level electrical resistors are divided into two categories: Fixed resistors and variable resistors. As the name implies a fixed resistor is the one which exhibits essentially constant value of resistance, whereas a variable resistor is the one whose … Read more
kW to Amps conversion provides helps to calculate kW from the known current amps in circuit. Let’s start off with four formulas: In case of Direct current: I = (kW * 1000)/E In case of single phase AC: I = (kW * 1000)/(E * PF) In case of two phase AC, four wire: I = … Read more
