How does a retractable cord reel work?
They work on a pair of rotatable wheels inside a storage space that houses the entire length of the cord. When a user pulls the cord, extending it, the ratchets lock automatically, preventing the cord from rolling back up into its original storage position.
Why does a coiled extension lead heat up?
Coiled cables restrict airflow to the cable, reducing the ability of heat transferred to the air to be dissipated by convection. That may cause the temperature of that air to exceed the rated ambient air temperature and reduce the ability for the heat to be removed from the wire.
Is it safe to use a coiled extension cord?
Extension cords that are coiled up can create a fire hazard, even those fancy cord reels are at risk, because flowing current generates heat, and when that heat cannot properly dispense because of the coiling, fires may occur.

Unless absolutely necessary one extension lead should not be plugged into another. account the current rating of the cable used for the lead. possible to draw a total current in excess of the 13 amps maximum for the wall socket.
Does coiling a wire increase resistance?
The simple answer is no. Winding wire on a non-ferrous form will not change its resistance. Of course, it all depends on the details. If the wire is uninsulated, and the form is conductive (copper, silver, gold, platinum, etc) the form will short out the wire turns and reduce the total resistance.
