I = 5,000 watts ÷ by 240 volts; I = 20.8 amps; Because the electric space heater on a continuous load could operate for three ...

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 operat… ...

This article is part of the Power Management Series: What’s the Difference Between Watts, RMS, and More?. Download this article in .PDF format. Both watts (W) and volt-amperes (VA) are units of ...

NAMM 2025: AmpRx has unveiled Brownie, an voltage optimising power supply that’s designed to give your tube amp exactly what it needs to perform at its best. Now, AmpRx has made voltage ...

Amps - Current. If voltage is the pressure of the water, amperage is the diameter of the hose carrying that water. Amperes, or amps, named after 18th and 19th century physicist André-Marie ...

When designing op-amp circuits, you’re often using a chip with 2, 4, 6 etc. amplifiers on the same die when you only need 1,3,5… so you end up with an extra.

Small car batteries work for 40 ampere-hours, while larger ones will easily last for 50. More oversized vehicles, like trucks, use batteries with 75 ampere-hours capacity. Car experts recommend paying ...

Most car batteries have 400 to 1,000 amps — sometimes specified as "cold cranking amps." Therefore, running two 800-amp car batteries in parallel would result in the same 12 volts, but a ...
