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. | \(13~\Omega\) |
