              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)
