When first learning about and building electronic circuits, the first things all of us come across are passive components such as resistors, capacitors, and inductors. These have easily-understandable ...

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and ...

It's only a circuit breaker. How hard could it be? A surprising number of engineers specify the wrong type of circuit breaker to protect their equipment. Engineers ...

DC Circuit Components provides a comprehensive overview of the different parts that appear in DC circuits, including source, path, control, and load. DC power sources include batteries, generators, ...

According to the most recent data from the World Bank, 15 percent of the world’s population—approximately 1.1 billion people—lacked access to electricity in 2014. In 1994, approximately 27 percent of ...

ProTek Devices has introduced its SM15KPAN series of high-powered surface mount transient voltage suppressor (TVS) components to provide overvoltage circuit protection in applications that include ...

This simple circuit tests speakers, microphones, transformers and voltage. It’s basically a very low frequency oscillator that produces extremely short ‘fruity’ pulses. The type of sound produced is ...

The motor full-load current ratings listed in Tables 430.247, 430.248, and 430.250 are used to determine the conductor ampacity [Sec. 430.22], the branch-circuit short-circuit and ground-fault ...
