Using the Animation Start the animation by either clicking Vce ON, which applies a positive voltage to the collector of the transistor, or drag the Vbe slider handle up to increase the voltage applied to the base. Applying more than about 0.6 volts will make the transistor base-emitter junction conduct.

Warning The PC parallel port can be damaged quite easily if you make incorrect connections. If the parallel port is integrated to the motherboard, repairing a damaged parallel port may be expensive, and in many cases, it is cheaper to replace the whole motherboard than to repair that port.
