Thrae qual resistors Connected in Sariesacxass a batter dissipate 10w PawerWhat will be-the-Pawer dissipated.tthoSame resis tor ae connecteal in parll-across the . Same battary

Answer»

When the three resistors are in series, effective resistance in the circuit = 3R.Power dissipated in the series circuit = Pseries= V^2/(3R) = 10 W ⇒V^2/(R) = 30 WWhen the three resistors are in parallel, effective resistance in the circuit = R/3.Power dissipated in the parallel circuit = Pparallel= V^2/(R/3) = 3V^2/(R) = 3 x 30 W = 90 W.
