Board-level designers often have concerns about the proper way to handle grounding for integrated circuits (ICs) which have separate analog and digital grounds. Should the two be completely separate ...

Resistors are small but essential components that manage how electricity moves through a circuit. This video explains how ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

What's the harm in objectionable current, and how do you eliminate it? You should know 250.6 says objectionable current is not to flow on grounding and bonding paths, but do you know what it is, why ...

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

Q. The Code prohibits "objectionable currents;" what is this, what are some examples, and how can it be prevented? A. Section 250.6 of the 2011 NEC addresses objectionable current. First of all, the ...
