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

1. \(230~\Omega\) 2. \(46~\Omega\) 
3. \(26~\Omega\)  4. \(13~\Omega\)
