P = V*I  Heat and Power - PEFI 2.7

   
 
   
 
   
  Try out the circiut for yourself

How warm does the Lamp gets?

What's the voltage at the battery when
the power is turned on?  

Is heat production good or bad?   

   

Electric Circuits - PEFI 2.11

   
 
   
 
  Try out the Combination Circuit yourself - will it be hard to get the 3 Volt ?
