              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)
