Plate 20.1 Uninsulated composition resistors, 

 rated at 3, 2, H, 1, \ and k^ 



Plate 20.2 Insulated composition 

 resistors, rated at i and 1 W 



Plate 20.3 Pyrolytic resistors, rated at 1, \,\ and \ W 



'1 r 



Plate 20.4 General purpose wirewound resistors, 

 conservatively rated at 15, 10, 6, 4^, 3 and H 

 W. Considerably higher dissipations than these 

 are possible, e.g. 6 W in the 3 W size and 30 

 W in the 10 W size
