Transistors have leakage current in collector base junction which is reverse biased.what actually is leakage current,and why does it flow,can u explain in in detail plz....

leakege current is the current that passes through the reverse biased and its sooooooooo smalll because the reverse biased resist the flow of current
thats all what i know

any kind of semiconductor material is not perfect. for eg. p type material have electron as impurity and n type material has holes as impurity. When reverse bias is applied i.e +ve voltage is applied to n side and -ve to the p side then impurities which are of opposite type got attracted and displced. This displacement or flow of opposite type of impurities create leakage current.
