Dear Friends,
Assume : current-water, transistor- as a pipeline.
Tranistor madeup of 3 parts: Base,collector& emitter.
Assume: base-valve, collector and emitter as pipelines via base..
(Transistor working principle- In simple words, When current passes through 'base' the switch opens which will make the 'collector'&'emitter' to paas the current through them). Think base as a valve when open(activated through current) this will make water(current) to flow from collector and emitter.
Try in the circuit close the switch to open the base valve which makes current to flow from collector & emitter and make BULB to glow.
Note: valve should be always open slowly else due to sudden water pressure the pipeline will burst. Same principle also works with transistor. In transistor the small current should be slowly pushed into the base, this is the reason the resistor is connected with switch with the base.
Regards,
Happy learning.
