              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)
