[Amps] Plate choke resistance

[R.Measures]

   Thinner wire allows more L per unit length, so the RFC takes up less 
space,  The reason that one can use thinner rather than thicker wire 
for a single-layer RFC is that since each turn is in contact with 
cooling air, the current capacity is increased.  For example, in HV RFC 
service, #22 Cu will carry 7A in SSB and CW service, whereas in xfmr 
service, it might be used to carry c. 1A.
-  Satisfactory types of insulation for HV RFC service are TFE or Type 
WL 180ºC silicone varnish insulated wire -- such as is used by electric 
motor rewinding shops.
