Vedclass · Answer

(A) $1$. In a $BJT$,the base terminal is common to both the emitter-base and collector-base junctions. When testing with a multimeter in diode mode,the base is the terminal that shows a forward voltage drop (typically $0.5 \ V$ to $0.8 \ V$) when connected to the red probe (positive) while the other two terminals are connected to the black probe (negative).$2$. In the image,the center terminal is connected to both red probes. This indicates the center terminal is the Base.$3$. Since the red probe (positive) is connected to the base and the black probe (negative) is connected to the other two terminals,the base is $P$-type. This identifies the transistor as an $NPN$ $BJT$.$4$. The forward voltage drop from Base to Emitter is typically slightly higher than from Base to Collector. Here,the reading $0.625 \ V$ (left side) is slightly higher than $0.623 \ V$ (right side). Therefore,the left terminal is the Emitter and the right terminal is the Collector.$5$. Thus,the configuration from left to right is Emitter,Base,Collector,and the type is $NPN$.
