hi, at page 183 of the pdf file it introduces the idea of a transistor as a switch and says "...lamp's current will move against the direction of the emitter arrow symbol". Please can you confirm the diagrams in figure 4.3b and 4.3c are correct becasue they seem to contradict the text; I have checked and checked again. Here I am using the word 'current' as a flow of positive charge ("conventional current") and I know earlier threads have discussed whether current means electrons or not-electrons. still in the diagram the poles of the battery are labelled... new to transistors I'm afraid!
