Two resistors of resistance, $$100$$ $$\Omega$$ and $$200$$ $$\Omega$$ are connected in parallel in an electrical circuit. The ratio of the thermal energy developed in $$100$$ $$\Omega$$ resistor to that in $$200$$ $$\Omega$$ resistor in a given time is:
1. $$4:1$$
2. $$1:2$$
3. $$2:1$$
4. $$1:4$$

A filament bulb ($$500$$ W, $$100$$ V) is to be used in a $$230$$ V main supply. When a resistance$$R$$ is connected in series, the bulb works perfectly and consumes $$500$$ W. The value of $$R$$ is:

 1 $$230$$ $\mathrm{\Omega }$ 2 $$46$$ $\mathrm{\Omega }$ 3 $$26$$ $\mathrm{\Omega }$ 4 $$13$$ $\mathrm{\Omega }$
