When the three resistors are in series, effective resistance in the circuit = 3R. Power dissipated in the series circuit = Pseries = V2/(3R) = 10 W                                                                           ⇒ V2/(R) = 30 WWhen the three resistors are in parallel, effective resistance in the circuit = R/3. Power dissipated in the parallel circuit = Pparallel = V2/(R/3) = 3V2/(R)                                                                                = 3 x 30 W = 90 W.
