Webb19 feb. 2024 · SW Ohio. Feb 14, 2024. #5. Can't always judge by physical size, if that's what you're alluding to. With most carbon comps and others relative to the same manufacturer, you can usually. But, I've seen some 1W flameproofs the same size as an 1/8 watt carbon comp resistor. Look up the data sheets on everything you order. WebbFor that, we us another formula: P (power, in watts) is equal to I (current) times V (voltage). So then our original 167 ohm resistor ‘uses up’ how many watts? P = I * V P = 0.030 amps * 5 volts P = 0.150 watts or about 1/6th of a watt. So in this case, a 1/4 watt resistor would work fine. But what if the resistor was 1/8 watt (0.125 watts)?
WebbMost of the 1/4, 1/2, and 1 Watt resistor series have a voltage rating from 250 V to 350 V. Generally, the higher the power rating, the higher the voltage rating. There can be multiple voltage ratings available for different resistor series of … Webb14 jan. 2024 · Most resistors found in small electronic devices such as portable radios are rated at 1/4 (0.25) watt or less. The power rating of any resistor is roughly proportional to its physical size. Note in the first …
WebbWhen a resistor, does not have a 4th band, which determines the tolerance rating, the resistor automatically assumes a +20% or -20% tolerance. That means that whatever the value is of the resistor, it can go above that value +20% more or -20% less, and the resistor can still be considered in good operational condition.
WebbThe size of every step is equal to: 10( 1 12) = 1.21 10 ( 1 12) = 1.21 Thus, every value is 21% or 1.21 times higher than the previous value in the series, rounded to whole numbers.
