The input transformer is likely to be the most expensive part of the entire project. As an alternative, a couple of 12 Volt car batteries could be used. The input voltage to the regulator must be at ...

Increasing the output voltage of IC operational amplifiers usually involves adding high-voltage external transistors. The resulting circuit then requires correction to retain its operating ...

How power works in a data center: What you need to know Your email has been sent Electricity is often one of the least visible elements of a shiny, state-of-the-art data center. Learn more about the ...

Assuming that they're in series, 6v nominally for alkaline, as low as 4.8 for NiMH. Batteries are specced in Amp-Hours, not amps--amperage is a rate, Ah is a quantity indicating the amount of energy ...

If you ever wanted to build your own tube amplifier but you were intimidated by working with high voltages, [Marcel]’s low-voltage tube amp design might spark your interest. The design operates with a ...
