WebNov 3, 2015 · A single kettle will be about 2 kW when powered from 120V AC but at 48V DC this will be about 16% of the power at 320 watts. Three kettles full of water gives you 960 watts. Add more kettles if you need more power. Bonus, after doing the test the water may be hot enough to recycle or even make a cup of tea from. WebJun 27, 2015 · Using a resistor will limit the current and I want to avoid that. Simple voltage dropping isn't efficient, and efficient voltage dropping isn't simple. The proper solution is a 24 to 12 V switching regulator, at the end of the wire, as you have surmised. Probably 5 dollars on eBay, free shipping to anywhere.

WebApr 12, 2007 · For 10 mA and 120 volts (rms), the resistor value would be 120 / .01 or 12000 ohms. R = V / I. The impedance of a capacitor C is 1/j (2*pi*C*f) where the frequency "F" is in hertz. The "j" is electrical engineering for the square root of negative 1. WebSince the speaker receives less power from the amp than it did without the added resistors, acoustic energy is lower and the amp sounds quieter. Combining the speaker and the 8-ohm resistor in parallel creates a 4-ohm load. Adding the 4-ohm resistor brings the load back up to 8 ohms but the signal is attenuated by around 6dB WebAfter a viewer requested how I built my simple load tester, I though it was time to make a video about it.

With higher voltages the current setting will be a bit more "jumpy" because the voltage on the potentiometer will change faster. You can add a resistor that has roughly the same value as the potentiometer between it and the + rail, this will bring the pot voltage down.
