Hi Bob, Thanks for the info. Two parallel 1K, 2 watt resistors would give you 500 ohms at 4 watts . . . A series string of ten 47 Ohm, 1/2 watt would give you 470 Ohms at 5 watts. A series string of
Comments inserted below: YES NO .. the power rating will still be 1/2 WATT ! NO .. the power rating will be 2 WATTS Power rating of a series string is the same as the LESSER/LEAST powered element. Do
Mea Culpa ... you're right! Don N8DE ________________________________________________________________________ Where do you get ICE bandpass filters & beverage matching boxes? The same place that pays
The usable power rating of the network would be a little less than 4 Watts because the power dissipated in each 2 Watt resistor would be less than it would be if he only used one resistor: 220/490=4

Hi Don, You must have been absent from class on the day they taught Ohms Law. I have NO IDEA where you ever got the notion that the power rating of a string resistors or a parallel combination is equ
