If the radius of any current carrying wire is less than the critical r...
Explanation:
Critical radius is the radius at which the heat produced due to the current flowing in the wire is equal to the heat lost to the surroundings. If the radius of the wire is less than the critical radius, then the heat loss is higher than the heat produced, which limits the current carrying capacity of the wire.
Adding electrical insulation to the wire reduces the heat loss from the wire, allowing it to carry a higher current. However, the addition of insulation also increases the thermal resistance of the wire, which can limit its current carrying capacity.
Therefore, the correct answer is option 'D' - the heat loss from the wire would increase. This is because the addition of insulation reduces the heat loss, allowing the wire to carry a higher current than before.
