              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)
