Problem

Two resistors, R1=30 ΩR_1 = 30\,\Omega and R2R_2, are connected one at a time to the same sinusoidal AC source whose rms voltage is constant. If the average power dissipated in R1R_1 is twice that in R2R_2, the value of R2R_2 is a) 45 Ω45\,\Omega b) 60 Ω60\,\Omega c) 15 Ω15\,\Omega d) 90 Ω90\,\Omega
