357120 Two bulbs consume same power when operated at 200 \(V\) and 300 \(V\) respectively. When these bulbs are connected in series across a \(DC\) source of 400 \(V\), then the ratio of power consumed across them is

357121 The power dissipated in the circuit shown in the figure is \(30\;W\), the value of \(R\) is
