              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)
