The potential difference across the collector of a transistor, used in – InterviewSolution

InterviewSolution

1.	The potential difference across the collector of a transistor, used in common emitter mode is `1.5V`, with the collector resistance of `3 kOmega`. Find (i) the emitter current and (ii) the base current, if d.c. gain of the transistor is 50.
Answer» Here, `V_(CE)=1.5V, R_=3xx10^(3)Omega,` `beta=50.` `I_C=V_(CE)/R_C=1.5/(3xx10^(3))=0.5xx10^(-3)A` `I_B=I_C/beta=(0.5xx10^(-3))/50=0.01xx10^(-3)A` `=0.01mA` `I_(E)=I_B+I_C=0.01xx10^(-3)+0.5xx10^(-3)` `=0.51xx10^(-3)A=0.51mA`
