This is a take-off on Mr. Marian’s “Simple Micro Ampere Meter Circuit” that utilizes active circuitry and an analog meter to make sensitive DC current measurements. A reader subsequently asked if it ...

This video provides a clear explanation of inductors and their role in electronic circuits. Inductors are passive components ...

This AC to DC converter circuit is capable of converting an alternative voltage within 70V – 260V range into a DC voltage within 180V to 350V DC range, so it can be used for 110V and 220V too. To ...

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create a ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

Georgia Tech is to develop circuit breakers for >1MW dc power links up to 100kV – with wind farms, electric aircraft and electric ships in mind. Direct current power transmission is more efficient ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

Note: The requirements outlined in this article are based on the 2011 edition of the NEC. Article 690, which consists of nine parts, provides electrical requirements for photovoltaic (PV) systems.
