I'm a beginner and trying to figure out how this circuit works (its a simple circuit that glows an LED when dark) :
schematic http://makezineblog.files.wordpress.com/2014/10/wp20_schematic_w_circle-transistor.png?w=1410&h=827 My confusion is when the light is present, wont the current still flow through the collector and base of 2N3904 ? This is connected in parallel ? How does this circuit work ? How is the LED portion of the circuit not closed when light is present ?
