Conduction in reverse biasing too?? Is it the case with transistor??
I have a mechanical analogy of diode in which a socket is provided with a one way valve. (figure 1st below). The arrow inside the circle shows the direction of motor pump. When there is enough pressure to lift the valve (barrier potential) the socket will let water go without any resistance( ideal). this would exactly work out like a diode in a circuit.
Now i connect such two sockets to form a "PNP" jnction. (BJT). In the common base connection the collector-base junction is is reverse biased. My fluid flow analogy says the water should flow through the first valve whereas the second valve should essentially not let fluid flow. But they say " Large current flow through that valve (collector= base)"
Where has my analogy gone wrong?? What actually causes the fluid (current) flow at a higher rate through the second valve (Collector-base jucntion)??
Thanks in advance
