Resistor Question

Post by jckid649 »

If you do not have 1 resistor of the value that you need can you tie 2 together that add up to that value and solder them in place to accomplish the same thing?

We all run into this from time to time. Doesn't matter how many you have - you will be out of 1 value or another. (1k 5W here now)
Either series or parallel to get the value you need.
Or the next nearest value. I tend to use whatever I have on hand.

To be clear, let me state the obvious. If you put resistors in series the total resistance will be equal to the sum of the individual resistors. Two resistors of equal value in parallel will result in half of the individual value.

For quickly finding the value of 2 paralleled resistors of different values I like to use R1*R2/R1+R2

Or you can just use this super duper easy calculator.
