              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)
