Paper Transistor Hack
Working principal
• As we know the resistance across the paper transistor when we power the circuit by DC voltage to the paper circuit the LED gets positive supply from battery directly and negative supply via paper transistor from emitter to collector and ultimately LED switch ON immediately
• When we connect an positive end to an base terminal the positive potential at the base is much higher than the negative so the negative supply is interrupted and LED will switch OFF
• The only difference between real transistor and paper transistor is it normally ON
• When applying base trigger it goes OFF
