Hi everyone,
I have a question about resistors in parallel...basically a little confused and would like some clarification.
I have a high powered LED I would like to power but have a very small footprint on the PCB as to where I can put the the passive components. I thought it would be easier to add extra resistors to beef up the current handling capabilities. To accomplish this I thought putting a bunch of smaller wattage resistors in parallel would work the best. However, I don't know that it would increase the current handling capacity.
Basically I need 33 ohms at 4 watts so I thought I would put in 4 (1) watt resistors in the values of (3) 130 ohm and (1) 150 ohm. Will this do what I am expecting it will do or does the current not increase with the additional resistors?
What I am asking is does (4) 1 watt resistors = 4 watts?
Thanks in advance,
Jeff
