A student is given a transister. He is asked to find ot the teminals of p-n-p transistor as emitter, base and collector. He is told that the terminal marked with red dot is emitter. He touches red probe with known terminal as emitter and marks other two lead wires as A and B. He measures resistance between emitter and lead A. Then measured resistance between emitter and leadB and finds that resistance increases. This shows-
