1/R = 1/R1 + 1/R2 can represent 3 fractions, like: 1/2 = 1/3 + 1/6;
in this case, R=2, R1=3 and R2=6.
If you need more help, post the FULL original problem.

Thankyou im sorry about the capital letters,I can not post the problem because there isn't one, i just need to understand the formula and do a report about it but i can't find any informaton about it,but i kindof understand now .So all u have to to is simplify the fractins to get R but what happenes if they give you a problem and some numbers are missing how would you solve it?I would apreciate if you could give me another example
thank you
thank you
Well, you could be asked to solve: 1/R = 1/3 + 1/6
Since 1/3 + 1/6 = 2/6 + 1/6 = 3/6 = 1/2, then:
1/R = 1/2
Solve that for R.
If you can't, forget about doing any "reporting"; you're not ready.
PLUS do not use "u" for "you" and the likes: teacher may deduct a mark!
