Plate resistor wattage
Webb2 dec. 2024 · What to Know. Power resistors are used in electronics to dissipate energy by controlling current flow and voltage. The power rating of a resistor defines how much power a resistor can safely handle before it begins to suffer permanent damage. Most electronics applications use low-power resistors, typically 1/8th watt or less. Webb10 feb. 2012 · So, if B+ is 200V and your plate load resistor is 100k, then P = 200 * 200 / 100000 = 0.4 watts. Even if you manage to swing the tube all the way open, though, it's …

Without looking hard I found resistors on Digikey for sale range from .0125 to 80 watts. Wattage means how much power the physical resistor is rated to handle. Webb5 jan. 2008 · One often forgotten thing is power rating of the resistor which takes precedence over the voltage rating. Knowing resistance R and it's power rating P you get max allowable voltage as V =sqrt (P*R). Example: R=100k, P=0.5W --->Vmax= 223V even though the rating is 350V R=220K can work with 330V etc. JubileeMan 2555 Member …
