Heath Rich · Answer 1

I think its 9.0397 Ohms

Explanation:

take the reciprocal of all the resistances: 1/15, 1/65, 1/35

then add them: = 151/1365

then reciprocal the answer: = 1365/151

And chuck it on a calculator: = 9.04 Ohms

I think this is right but I'm not entirely sure. Tell me if I'm right by the way!
