Sir I am not getting answer of 19th question
which formula we used for zener diode??
i want to ask questions :
1 ques .. the current gain of a transistor is 50 . the input resistance of the transistor , when used in the common emitter configuration ,is 1kohmn . the peak value of the collector a.c . current for an alternating peak input voltage 0.01 v is ??
2 ques ..in a n-p-n transistor circuit , the collector current is 10mA . if 90% of the electrons emitted reach the collector then the emmiter current (IE) AND base current (IB ) ARE given by:???
3 QUES.. the minimum potential difference between the base and emmitter required to switch a sillicon transistor "on" i approximately:??
4 ques. in common emitter transistor , collector supply voltage is 15 v if current gain = 100 , base current is 5 uA and collector resistance is 5 k ohm then voltage across collector emitter is :???
5 ques .. a zener diode connected across a source voltage of 12v such that 6 v drops across it . the power drawn by zener diode is 2.4 mw , then what is the maximum value of series resistance connected in the circuit ???
does only electron having 0.7 ev diffuse??
why cant the electrons reach the conduction band with 0.05 ev ? in p type just like n type
