Some questions about bipolar junction transistors

[Plecto]

Hi. I feel that I have decent knowledge when it comes to mosfets, but there are a lot of thinks I simply don't know about BJT's. With fets I can find Rds(on), Id leakage, gate capacitance and then calculate the time it takes for the fet to turn on and off, but how does this relate to a BJT? What is the turn on-time, leakage current and resistance of a BJT? This might be the wrong questions to ask, but rather, what is Ic when Ib=0? What is Vce when Ic<Ib*Hfe? I keep wondering if BJT's are better than fets for battery powered operations (if it has lower leakage current) or for high current applications (if it has a lower voltage drop). Can someone please clarify this for me?

Hi,
Why don't you study this...very well explained every concept of BJT in details...

Thank you, but that seemed way over my head. I just curious about the few questions I asked in the opening post.
