Vintage Resistance Coil - 5Ω

£ 7.00
Wire-wound resistors are made by having a metal wire wound round a non conductive core. Each end of the wire is then attached to terminals on either side of the core. The wire is typically protected by a layer of paint or other material to form a hard, protective surface.
The advantages to wire-wound resistors are typically in the high thermal resistance of over 400 degree centigrade. Unfortunately, they also have the effect of having a greater inductance than other resistors, which can be mitigated by winding the wire in an alternating direction.
This resistance coil is rated for 5 ohms. It has had the wire wound loosley round a wooden core with a strip of fabric securing it in place. In good condition.
