Horsepower to kilowatts (hp to kw) Converter
Horsepower and kilowatt are two different units of measuring power. Watts is the SI unit of power. It is a well-defined and normally used unit. This is a simple tool…
Voltage division rule | Potential divider circuit
The voltage division rule is one of the basic rules of circuit analysis. It is applicable to all series and combination resistor circuits. A series connection of resistors always acts…
Series and Parallel circuits
Series and parallel connection of lamps Current flow in a circuit is determined by the impedance offered by the circuit components, which is in turn determined by the way circuit…
Contactor – Construction, Operation, Application and Selection
A contactor is a switching device, widely used for the switching of motors, capacitors (for power factor correction), and lights. As the name indicates it is used to make or…
Difference between MPCB and MCCB
Motor Protection Circuit Breakers and Moulded Case Circuit Breakers and are devices used to open and close a circuit manually and interrupt the circuit automatically on the occurrence of faults.…
Difference between RCCB and RCBO
RCCBs and RCBO are residual current protection devices. Residual current protection is achieved by monitoring the flow of current in the line and neutral. In a healthy circuit, the current…

What will happen if a DC voltage is applied to a transformer coil?
This is a quite common question asked by many. In fact, it is necessary to know why we don't apply DC voltage to a transformer coil. You may come across…
Difference between MCCB and RCCB
Difference between MCCB and RCCB MCCBs and RCCBs are circuit protection devices with two different application. When the former protect against overload and short circuit, the later protects against Residual…
Difference between MCB and MCCB
MCBs and MCCBs have commonly used circuit protection devices. These devices provide protection against overcurrent and short circuits. In this article, let us discuss the difference between MCB and MCCB.…
