# Can you "Daisy Chain" resistors? Answered

Can you chain together multiple resistors to add up their ohms into a larger amount.

Yes.  Resistances add, for resistances wired in series.  For resistors wired in parallel, conductances add, where "conductance" is the inverse of resistance.
( Γ = 1/R)
See:
http://en.wikipedia.org/wiki/Resistor#Series_and_parallel_resistors

Example:  A 220 ohm resistor and a 470 ohm resistor are wired in series.  The combined resistance of these is 220+470 = 690 ohm.

Suppose these same resistors are wired in parallel. The combined resistance will then be 1/ (1/220 + 1/470) = 149.86 ohm

Yes. It is called putting them in series. (see fig. 1) And the resistive values add together. A + B + C
fig. 1)  - - -      (one minus sign = one resistor)

There is another configuration called parallel(see fig. 2) and the resistive values add inversely. 1/A + 1/B + 1/C

Additionally, there are more rules to deal with when it comes to power dissipation, amperage handling and such.
