Question

If two resistors are connected in series the effective resistance is 45 ohm and if same resistors are connected in parallel the effective resistance is 10 ohm find ratio of two resistors

Answer 1

See the pic I hope you will get it...

Answer 2

Answer:

Explanation: in case when two resistors are connected in series

Rs=R1+R2

let R1=x

so, R2=45-x

Now when they are connected parallerly total resistance i.e. 1/Rp=1/R1 +1/R2

means 1/10=1/x + 1/45-x

then you can find the value for x

hence value of both resistors.
