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 ...

Extending Woodward's original "Flip ON Flop OFF" for AC voltages, switching power ON and OFF using a pushbutton or a ...

More than 100 years after alternating current (AC) defeated direct current (DC) in the so-called Battle of Currents and became the standard way electricity was delivered, new technologies have ...

Although inductive and capacitive circuit elements are affected differently by AC and DC, resistive elements behave the same under both conditions. AC circuit analysis methods are more involved than ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1.This is why it’s so important ...

In an initial test, this circuit was able to efficiently convert AC currents into DC signals at liquid helium temperatures (e.g., those attained using closed-cycle refrigeration techniques).

By manipulating the switching frequency and turns ratios of the transformer, the circuit can have an arbitrary output voltage. In this case, it is designed to take 220V AC and convert it to 8V DC.

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

PTVS diodes are offered in a wide voltage range with surge current ratings of 3, 6, 10 and 15 kA to deliver protection advantages compared to MOVs in typical AC and DC power line applications.
