              the resistor              
 it resists  electricity. it can  be good 
 or  bad at  this  and  this  property is 
  measured in ohms. resistors practice  
  aposematism, showing with colours how   
           dangerous they are.            
                                          
             the capacitor              
 this   is  an   ephemeral  battery   and 
     voltage multiplier, used for load    
        balancing and for defence.        
                                          
             the lodestone              
 stores a  position in a  magnetic  field 
   and outputs electricity when moving    
        closer or further from it.        
                                          
           the schottky diode           
 this  component   limits   the  flow  of 
 electricity through itself to go  in one 
             direction only.              
                                          
           the mustelid probe           
     measures distance to (uncloaked)     
                 ferrets.                 
                                          
             the cat wire               
 a  wire  used  to  connect  machines and 
         appliances to each other.        
                                          
               the slower               
 slows  down  the operation of  a circuit 
                                          
               the furnace              
    exports daemon energy through. some   
               kind of hole               
                                          
                              
                                          
                                          
 not  covered:  water  circuits  (see  my 
 post  on  submerging  a  magic spell  in 
 water   for   details   about   how   to 
             implement them)
