Distribution Board Wiring Diagram – How to wire DB
Distribution Board or DB is an electricity supply system or a common enclosure that distributes the electrical power feed into subcircuits. It includes isolator, RCCB (Residual current circuit breaker) or RCD (Residual-current device) devices, protective fuses or MCB’s (Miniature Circuit...
Send GPS Location Via SMS GSM Arduino
The main three components in this project are GPS (Global Positioning System) module, GSM Module, and an Arduino Uno. Here we are sending the live coordinates received by the GPS receiver module to a...
Arduino Ammeter – Measure DC Current
An ammeter is an instrument used to measure current flow in a circuit, which is measured in amperes. In a Digital ammeter, we measure the voltage across a shunt resistance, which is series to...
Different Types of Rectifiers and Working
A rectifier is an electronic circuit which converts Alternating Current into Direct Current. Based on the type of input supply, rectification and output it can be classified into different types. Single Phase Rectifier Single...
3 Phase Rectifier – Half Wave and Full Wave
A 3Φ Rectifier is an electronic circuit that converts three-phase AC supply into unidirectional DC output. 3 phase rectifiers are mainly used in industrial and high power applications. In a three-phase electric power, an alternating...
Why Are Printed Circuit Boards Usually Green In Color?
Commonly PCBs are made of glass fiber reinforced epoxy resin or fiberglass board which naturally has a greenish color. And the outer layer of the PCB is a solder mask that is what we...
Operational Amplifier Viva Interview Questions and Answers
What is an op-amp? An operational amplifier is a direct coupled high-gain electronic amplifier with a differential input to which feedback is given to control its response characteristics at its single-ended output. What is called a differential...
