MPSC State Service 2017 · GS · Question 56 of 100

If two resistors are connected in series, the total resistance is 45 Ω and if the same resistors are connected in parallel, the total resistance becomes 10 Ω. Find the value of the individual resistors.

Physics

Answer: D. 15 Ω, 30 Ω

R1 + R2 = 45 and R1·R2/45 = 10 gives R1·R2 = 450; solving yields 15 Ω and 30 Ω.
