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 ...

Here is a simple 12 volts DC to AC inverter circuit. This 120V AC power source is built with a simple 120V:24V or 110V:24V center-tapped control transformer and four additional component. This circuit ...

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.

However, you need to measure the peak value as well because electronic loads care about the peak value, since that's what they use to power their AC-to-DC conversion circuits. When almost all of the ...

Famously, Nikola Tesla won the War of the Currents in the early days of electrification because his AC system could use transformers to minimize losses for long distance circuits. That was well ...

Fuses protect against overcurrent events by melting their elements and opening the circuit. Fuses must be applied at or below their specified voltage rating, which differs between ac and dc ...
