A uniform heating wire of resistance \( 36\,\Omega \) is connected across a potential difference of \( 240\,\text{V} \). The wire is then cut into half and a potential difference of \( 240\,\text{V} \) is applied across each half separately. The ratio of power dissipation in first case to the total power dissipation in the second case would be \( 1:x \), where \( x \) is:
