i am trying to understand how current flows in a BJT NPN and how amplification happens at the collector current ?

pls refer this link: http://www.learningaboutelectronics.com/Articles/How-to-connect-a-transistor-in-a-circuit-for-amplification

as per books when we connect a Vcc supply to NPN ic flows from Vcc to the collector but they also say amplification happens when minority and majoiry carries replace and diffuse from base into collector and a current fflow comes which is amplified

cant understand how its amplified ..as per circuit laws vcc gives ic which flows into the NPN collector then how this current is amplified as it depends on the load resistance really absurd ..help me ..don give bookish answers

This is the way I understand it: a Vcc supply to NPN Ic flows from Vcc to the collector but they also say amplification happens when minority and majority carries replace and diffuse from base into collector and a current flow comes which is amplified.

I cant understand how the current is amplified as per circuit laws. Vcc which gives the collector current which flows into the NPN collector. How is this current amplified? as it depends on the load resistance.
