**MathMate**, Tuesday, May 31, 2011 at 3:57pmResistors in series have an equivalent resistance of the sum of the individual resistances.

Here we have three resistors with individual resistances equal to 10, 40 and 70Ωs. What is the total resistance?

**Anonymous**, Tuesday, May 31, 2011 at 4:47pmdo I just add them up?

10+40+70=120
