A potential difference \( V \) is connected across a device with resistance \( R \), causing current \( i \) through the device. Rank the following variations according to the change in the rate at which electrical energy is converted to thermal energy due to the resistance, greatest change first:
\( R \) is doubled with \( i \) unchanged.
