☆Hey dear here is ur answer.....☆
The coil of resistance box is made of double wire to avoid the induction and heating effect. and also to increase the resistance and to decrease the voltage.

The wires in the resistance box are double folded and thus coiled to nullify the inductance effect.
- In the resistance enclosure, wires are normally double folded and coiled to nullify the effect of inductance. Because of this magnetic induction caused by half of the wire, the magnetic induction induced by the other half of the wire is cancelled and the wires are preserved with pure resistance.
- A wire's resistance is proportional to the wire length. The resistance will double if the wire is double. Therefore, by doubling the wire between the nodes, the resistance box can have high resistance.
