Question

for normal operation of pnp transistor the base must be + or - with respect to emitter and with respect to collector?

Answer 1

Answer:

The voltage between the Base and Emitter ( VBE ), is now negative at the Base and positive at the Emitter because for a PNP transistor, the Base terminal is always biased negative with respect to the Emitter. Also the Emitter supply voltage is positive with respect to the Collector ( VCE ).
